I have noticed that the nicer I look, the faster I get hitches. For a while, I only had one white shirt that quite quickly became a dirty brown shirt. The longer I traveled, the dirtier it got, and the longer it seemed to take to find a ride. I eventually ended up losing the shirt somehow (sadly I've taken it a lot of places) and quickly I found a polyester blue golf shirt in a laundry Matt. I looked like a college kid on a vacation, instead idea homeless traveler. I quickly started getting rides in as much as half the time as before.
