took a ride from oklahoma city once in i 40 or 45 watever the fuck it, over to amarillo at like 11 at night. the guy drank a whole 6 pack and a couple of cans of beer. he swerved a tiny bit. nothing that worried me though. the guy was from an oil rig. in mexico, and texas. it was obvious he knew how to drive a truck and drink beer and be fine. and it took me about an hr of riding with him to figure this out. now it takes me les than a min my mind works too quickly. i can talkt o u for a few minutes and know all about you. city people are people with cars are usually pretty easy to figure out.
if it dont feel right dont do it. better safe than sry.
