The best sign I ever stole was from a military base:

I have twin nieces, who are 16 years old, and high school juniors. I keep hoping that the one named Abigail decides to go to college at Illinois State University, in Normal, just so I can call her “Abby Normal.” 
I work in the GIS department for county government. One of our jobs is to approve new road and subdivision names.
The big problem is duplication. That really screws up EMS. A lot of developers put the cart before the horse and spend thousands in promoting their new project before getting it approved. It really pisses them off when we have to say no to their project or road name choices.
We have regulations about what is a duplicate, but it can still be sort of subjective. You just can’t right a rule that covers everything. We do have a Barking Dog Rd which I like. That’s not a duplicate.
We allow people to rename a road if everyone living on the road comes to a consensus.
I live in a different county than I work. The county I live in was going to rename a bunch of road names because of duplicates. We could make suggestions. They wanted a bird theme for my area. I’m the only full time resident on my road and was going to name it Chicken Crossing Road.
(my bold) Why would you want to? Wouldn’t that make it wrong?
You need a sign on the side of the road saying, “The Other Side,” à la Gary Larson.
God protect us and guide others!
The constantly-changing-road-names are bad, I agree. I’d even go so far as to call it bad bad bad, after you-know-who. (Are your ears burning, @Beckdawrek ?)
I have nothing but respect for GIS. The creators of that “religion” wove together lofty dreams that showed a neat, tidy world, with everything interconnected and playing nicely together. When fully implemented, some time in the 24th century, all land data will be packaged together and easily accessed with a click (or two, or five…) of a mouse.
Road names are bad enough. But God help us all in finding a lot number!
When we bought our property in 2000, our land was known as Lot 152 of the subdivision.
The mailboxes just off the main highway gave us an address of the mail route number, and an individual number concocted from the post mile and how many people had requested mailbox numbers before us.
It was easier to rent a PO box.
Eventually, the County gave our private dirt roads within the subdivision their own “names.” Our dirt road is N9301. To facilitate UPS and FedEx, we would refer back to our original lot number from the subdivision. Our physical address was now “CR N9301, Lot 152.”
Neat. Tidy. Reasonable.
The fire department said, “Uh, no. That won’t do.” We are still on CR N9301, but the Fire Service number is “500.”
That’s already screwed up UPS delivery. And UPS used to be able to find our house, no problem!
Now, for the cherry on top!
We got a letter from the County, telling us they finally got their GIS ducks in a row. And of course they had to use their strange alchemy to give us yet another lot number.
Of course!
The County supposedly coordinated with God, the Fire Department, and Cinderella’s Fairy Godmother to proclaim our *new, improved" lot number of 132.
My head hurts. I’m gonna take a pain pill and go back to bed.

Our neighborhood has 673 distinct roads that all start with Bahia; every combination you can think of – Bahia Rd., Bahia St., Bahia Circle, etc… GPS is no help when people need to come out to the house, so we specify in big letters in texts which street to look for. It wouldn’t be half bad if the house numbers were graduated (e.g., our road has #1 - #28, a different Bahia road starts at #100, another starts at #1000, and so on but, NO, every street starts at #1 [or #2]), but that would require cleverness and no one’s clever Friday afternoon at 4PM. 
It sounds like Bahia is your area’s analog to Peachtree in Atlanta. Every third damned street in Atlanta is Peachtree something-or-other; I have no idea how anyone found anything prior to GPS.
If you haven’t updated your GPS subscription, you’re still out there – lost forever in suburbia (an Irwin Allen production).
The next neighborhood over is Pine. 
Sounds like you need to get familiar with What Three Words. They’ve divided the world into 3-meter squares and assigned a unique three word for each one. That phrase can be shared via the usual paths and can be used to locate that particular square.
That. Is. Clever.
I can’t wait to see the bickering when businesses are jockeying for just the right combo to augment their advertising.
Sorry, I’m in a mood. 
If you come out to my house (my road is informally our surname) you’ll end up in a lake, if you follow GPS, I promise we live above water.
Our road ‘number’ is the same as a major highway number. There’s no use trying to explain it to anyone. They never understand.
Like @VOW said, it was easier to get a box at the post office.
You live on Dawrek Rd.?
Sorry, I’m in a mood. 
Yeah. That’s similar to living in ski country in the mountains. Lot’s of wildlife too. Anything with an Elk or Bear or whatever name is right out. So is Ski anything. I don’t know how many Lake Views we have (happened before regulation).
And before regulation, the developers where allowed to assign their own address numbers (not just street names)
So a 3 story condo might have 600 as the first story, 6000 as the second story and 60000 as the third story. Address numbers are supposed to get bigger as you proceed on a road. Not when you go up in a building. It’s a total mess, and I hope I retire before trying to tackle that.
Yeah, I got a box at the UPS store in town. It’s an address. Anyone will ship to it. Most systems will find our house, but if you don’t have a good 4 wheel drive in winter, well good luck.
It’s works well for us, the UPS store emails me when it comes in, and I go into town two or three days a week anyway. So I just pick it up.
I could live there.
Sorry I’m on the goofballs again.
It’s all well & good until you start seeing Perry Mason. 
The best 69-related road sign is on I-75 near Detroit and has given giggles to generations of teenage drivers:
Now that is a remarkable confluence of exit numbering and street name.
So it’s not just us in the UK, then. I post on travel messageboards, and it’s a regular thing for US visitors to be reminded not to truncate street addresses: because there may be the same sort of variations (X Street/Square/Avenue, etc), which might not be near each other, and because it might be the same as somewhere up the other end of the country - ask in London for directions to “Liverpool” and you may be sent to Euston station for a 200-mile train ride, when what you really wanted was Liverpool Street.
