Interesting article circulated by Functional Transit on fare free transit. In terms of paying for it, a possible funding approach (similar to the U-Pass) would entail every person over 18 years old paying for a monthly bus pass equivalent (with specific exceptions) whether they ride transit or not. This could provide even more funding to enhance and expand transit services than the status quo.
