I suspect it’s easy to get a free bus pass. While visiting SF it was easy to get off the bus, get a day or two’s food, catch another bus and go miles to where we were staying.
The bus fare for HART (Hillsborough Area Regional Transit) is $4 for an all day pass. If we want to, we could go to either Target, WalMart, Publix, Winn-Dixie, The Fresh Market, Whole Foods or Trader Joe’s on the bus. We usually bike to either Publix, Winn Dixie, WalMart or Target. The nearest store from us is 3/4 of a mile. It is good exercise.
