I know there's a bunch of other Steemit users in Jersey, I guess it depends on how many are close to there and / or how many people from Philly might also be willing to make the trip. Planning a meetup is relatively easy though, making it a success mainly comes down to managing a lot of small details.
I'd be glad to help you work on that if you're serious about. Email me -> [email protected] and we can discuss. Cheers.
