I suppose this isn’t weird for the Miami folk but when I was going to Miami Internatinal Airport, I was stuck in traffic and noticed that there are* Iguanas * in the trees along the river. We were in serious traffic and I could probably have gotten out of the car and picked one up if I’d been especially dextrous. And then a little “Chicken of the Trees” for dinner…
While on a bike tour in Oregon I stopped by the side of the road and went behind a big tree to take a leak. I almost stepped on a beautiful but very dead deer. Maybe it’s not unusual but it was still disturbing.
Once you know what to look for, those piss bottles are all over Chicago. Especially near highway ramps.
Oddest thing I’ve ever encountered was in rural Michigan. My dad and I had gone to a car show and we developed an overheating problem. We’d drive a few miles and then have to pull over for 20 minutes of so and go again. Anyway, it was a long 200 miles home. To entertain myself during the cooldown periods, I’d walk the grassy area between shoulder and whatever farmer’s field we we next to. There, in the grass, was a photo negative of a someone’s gel electrophoresis. Blowin’ there in the wind, miles from anywhere.
But why can’t they be bottles of applejuice? 
Beside a barn - near the side of the road - I saw a camel.
Everyone in the car accused me of not wearing my contacts, so we drove back. It was indeed a camel.
How about this? http://boards.straightdope.com/sdmb/showthread.php?t=280442
Today, I saw half of a football helmet. It was purple with a white and yellow logo. I don’t know the colors/logos of the local high schools, so I have no clue of its provenance. I was just concerned about the head of the person who once owned it, since it was sheered neatly across the crown, from earpiece to earpiece. (I saw the front half, with the face guard still intact.) I’m hoping that it was part of some kind of art installation, and that someone took a saw to it after it was retired from use.
The weirdest thing in the curb at my house was a dead skunk (thanks, Loudon). The smell made me gag.
I also was walking in the curb and came one step away from stepping in a road kill possom. I urped on top on it.
We live in Texas. Spring rains and cool temperatures will trigger the bluebonnets to burst from the roadsides.
One year, Cardsfan and I were heading to Fort Worth and got stuck in the worst damn traffic jam I have ever seen in my life. Four lane highways became a parking lot with traffic barely moving. It took us 2 hours to figure out what the traffic jam was all about…
People had stopped on the side of the road, gotten their kids out of the car and trudged up in the middle of the road medians to take pictures of those precious darlings sitting in the middle of the bluebonnets. :rolleyes:
I mean the flowers are pretty to look at, but good gosh don’t stop traffic galking at them!
Last year there was a dead man lying by the side of the road whom I passed on the way to work. A couple of years before that, my morning commute included a woman’s head. According to reports she’d been decapitated by her seat belt when her car rolled. But those really fall into the horrible/wish I hadn’t seen them category.
For just plain weird, I was stopped in traffic on some freeway in LA when I noticed a pile of used condoms by the side of the road. Two or three dozen used condoms of various colors. Someone cleaning out the back seat? I still wonder over that one.
Then there was the goat my dad and I found. We were cleaning trash along the highway in front of our property when we meet this little goat. This is especially odd because we lived thirty miles from the nearest town, in the middle of the desert. Our neighbors took him in and eventually, well, he was delicious.
I was getting on the DC Beltway and I saw an antelope.
Yup, antelope.
I only got a glance at it, but I had the definite impression of a striped head and swept-back antlers. I dunno, logic says it must have been a deer (See the thread already linked above) or maybe a goat. But my pattern-recognition software said “antelope”.
Has the pronghorn come east? (Perhaps to complain about the current administration’s environmental policies?)
While driving down the highway in the middle of Chicago, I saw a dildo lying in the middle of the road.
I turned to my (then) wife and said, “Looks like Lorraina Bobbit was here”
- Lady trying to commit suicide by driving off the road
- 3 large flaming rings along a hillside
- at least half a dozen flaming cars along the side of the road (not crashes)
- An 18 wheeler taking a short cut through a field at night (got stuck).
- My water pump pulley wheel at an intersection (so that was what that noise was)
