I’ve made several 8- 10- and 12 hour road trips solo. The first time when I was 22 and moving from Ohio to Florida (16 hours split over two days)… I thought might kill me. I got to Jacksonville and called my mom. Conversation went like this:
DZ: Hi Mom! I’m in Florida!
Momzilla: That’s great! You made it!
DZ: No, I made it to Florida. I still have 300 miles to go. I’ve been in the car for a day and a half. If you ever want to see me again, send a plane ticket because I am never doing this by myself again.
Momzilla: LOL
Because I don’t do it all the time and have never been afforded the luxury of being able to drive a good driving car (like a Beemer), I find my upward driving limit is really around 6-8 hours. I can go 8-10, but I’m pretty worthless after about 8 – and therefore, not very safe. My rule of thumb is if I have to drive more than 6 hours, I look into flights. In your case, however, I’d recommend taking an extra day… maybe even two.
Aside from bringing a small cooler and taking little walks on pee breaks, I also recommend making one or two one-hour stops. Go inside a restaurant and sit down to eat. Take a 20-minute walk. Pick up some extra whatevers at a drug store or something. Walk through a mall for a minute (I actually called my mom from inside a mall I’d spotted from I-95).
And now, another little anecdote to think about.
Many moons ago, I had a group of friends who were, for some reason I can’t remember now, driving from Ohio to Montana (or maybe it was the other way around, doesn’t matter). There were four of them on this road trip and they had it in their heads that they had to be at their destination by a certain date, so they drove straight through, taking turns, on something like a marathon 35-hour road trip. (Or maybe longer. Seems like “four days” is in my head for some reason.)
About a year later, one of the guys on the road trip was stricken with some horrible dreaded young-person cancer and died. On his deathbed, he was talking to one of the women on that trip and said, “Remember that trip we took across the country? That was so much fun! We were in such a horrible hurry to make time, we practically killed ourselves getting there. Only now I can’t remember why we were in such a hurry? What was our rush?” My friend said she really couldn’t remember as none of them had jobs at the time and they really had all the time in the world they could have used to enjoy this trip. And now our friend is gone and there will be no more road trips for him.
So, I ask the OP… what’s the rush? Why not take a little extra time to see some sights and meet some people and enjoy the trip?
