This is cool! Portland's Streetcar is blazing the trail for the nation.
What I like about Portland's public transit model is how the downtown, extending to the other side of the river (upto Lloyd's Center) is free. It makes it very easy for people to go from PSU to Powell's or Lloyd's Center and now OMSI without having to use your car.
Portland's public transit is one of the best in the nation and it just keeps getting better.
Way to go, Portland! (And thanks, Atrios, for the heads up.)
