If so, know a good route from the Northeast (Mayfair/Frankford area) to Center City? I'm thinking straight down Aramingo might work pretty well. There's always Frankford/Kensington under the El but that seems like it'd be a little sketchy.

toresdale to Aramingo is the way to go. curch st. is the best connector. Just hop off at lehigh and head over to delaware ave. then follow that down to spring garden, which you can take across to where ever you want to go.

only downside is that aramingo can be busy around all the shopping centers. Just make watch for cagers...

I commute in Northwest Philly, and all my trips to center city go through west philly, on Market Street. So I'm not entirely sure.

Thanks guys, looks like Aramingo is my road. Seeyas out there maybe.
