Usually community service is fairly lenient in where it is done, usually as long as you have a letter from a Philly nonprofit (or one outside the city stating the CS was done in the city) City how many hours you worked for community service, you're good to go.

I think it's a great alternative to jail for non-violent crimes and is usually a win-win because oftentimes the person performing it chooses something they at least don't hate and there's a decent chance that they will voluntarily get involved in more of it in the future.
