To Fix Georgetown:

Make Wisconsin pedestrian-only (as in no cars) from "R" street down to "K". Run two free trolley cars that entire length, one climbing when the other descends. Make "M" street pedestrian-only from Key Bridge to 28th street (where Pennsylvania Avenue starts). Run two free trolley cars that entire length, also, one going west when the other heads east. Lay some nice material down on the streets for foot-traffic, maybe looking like the old cobble stones, deciding whether to go with horse-drawn vehicles only or to make it comfortable for bikers, roller bladers, skateboarders, Segway riders, etc. THAT would make a destination. Hollywood (and the world) would want to make movies there. It would be the best neighborhood sight in D.C.
