Driving to work this morning, on the side of the road I saw a pair of ordinarily-dressed girls trying to hitchhike. (Ordinary dress - pants and shirts, not power-suit and the like.) This on a road that goes into the heart of town.
The interesting thing: bus-stops are all along that road, every block. There are buses which stop there every 10-15 minutes.
It only costs about $1 to use the bus from my place (edge of town) to the center of town. From the center of town you can catch another bus (another $1) to go to any one of two other smallish, nearby towns. Both of those towns are basically on the beach. You can go to several places for things like libraries, parks, shopping, food, banks, etc. There's even a couple of good-sized malls on the various routes.
So why where these girls trying to hitch a ride at the height of morning "rush-hour"? (I say "rush-hour" because it's nothing like a city's rush-hour - just streams of cars that are a bit clogged-up for about 15-20 minutes. Then it calms down to almost no traffic again.)
Too cheap to spend a couple of bucks to get where they're going.
