"hitchiker!" ...which I'm thinkin would be good for places where there arent many hitchhikers, Michigan, for example. Shows ya got a chipper attitude & plays into the fact that a HH is a rare sighting for the driver. Combine the two, they just may go for it.
You know, its real interesting, this social relationship between you and those behind the wheel. You have a sign, your person, and a few seconds to establish your nobility to a complete stranger. The words you chose for the sign are limited to what the drivers can see and read in that small period of time. You're really a bit of a slave to the stereotypes of the world. For example, a band I like called Pentagram I have a shirt of. Its got a big pentagram on the front. Now walking down the street with this shirt on I got no problem with, but theres no way Id be wearing it hitchin - no one in there right minds gonna let me in with that on, I'm a damn devil worshipper lookin for some ripe virgins for a ritual, obviously. When you've got your own transportation you can let your beard grow to the floor, hitchers, they gotta keep it in check. Its like a job interview - yea man, its just like a job interview, 'cepts its a damn quick job interview. Your paychecks a ride and they get to not feel guilty/converse/feel like they did good, etc. I havnt any experience in the HH arena, pickin up or hitchin, but what it seems like is people go with there instincts on these things, so it would seem the key is in putting out a positive energy...with your sign, the way your standin, if your smiling. Do that, and just wait.
