Back before my real job, once put on 86k in one year between the east coast, Montana, Idaho and Canada for the love of one sport. Knew a couple of guys who actually put more on in mileage than myself. Then it was fun, didn't think anything of it, and some great memories.
Now I drive alot for work, between two vehicles average about 50k a year. Really don't think about it, but all things considered, probably would rather do something else. Hate the jobsites that are in the 200-400 mile range. Rather fly, but by the time you get to the airport, get a vehicle and deal with security, just figure your better off driving, works to be the same amount of time, plus I get mileage soI can't complain.
Did bring back a memory. When my dad first taught me to drive stick, I used to drive him up the wall stalling and grinding gears and such. He's in his mid 70's now, and while we were taking an out of state drive together, he told me he would drive for a while. Chevy truck, 5 speed at the time. He took over, came up to a toll both and as he was slowing down, stalled the truck while trying to shift gears (while grinding some) and I was going crazy with what he was doing.
After we paid the toll, I thanked him. He asked me what for and I told him for not killing me with what I did to his car when he taught me to drive stick. Funny when you grow up how you realize what you put your parents through.
