Ass, Ass, or Ass
I've never picked up a hitch-hiker and I can't imagine any scenario in which I will at some point in my life. Maybe if I was traveling with a number of friends and there was a kindly old person with no arms and they were naked. Actually I'd like to support hitchers and help to forward the entire hitch-hiking community, but what about murder? I mean, back in the 50s we didn't have murderers so I'm sure it was fine to pick up strangers but you have to be careful ever since they gave people the ability to end lives.
Anecdote Adventure
Once when I was going to FSU I was going to gainesville for a weekend to meet up with a friend and I got someone to drive me to a spot just off I10 on I75 so that I could get picked up by my other friend from gainesville. You see, inconveniencing two people just a little is better than inconveniencing one person a lot. So, as I was waiting outside a gas station for the gville connection to arrive, a couple of guys (possibly nam-veterans, but maybe younger) walked up and struck up a conversation. They were asking where I was going and stuff like that and I told them and they asked how long I'd been on the road and that's where I made the concious decision to not correct their assumption (some call it lying, others call it 'acting') since they had already pegged me as a drifter and I didn't want them to think I was just some college kid on a weekend jaunt across the state. These people were real, living lives, and I was just the dude doing what I was supposed to based on my background. So I became a drifter, but I hadn't been out long and I was getting picked up by a friend to visit for the weekend (both true!) and so we were able to continue our discussion. I asked about their backgrounds and I've unfortunately let their details slip from my mind and they advised me that I should get a dog, because it puts people at ease and it's good fror protection. My ride came, I said goodbye, we shook hands, and I got in the new silver honda and rode off into the sunset. I gotta clear my colon.
