Where in upstate NY are you?
There are two ARMA study group in NJ, but that's not going to help you any. There is a HEMA group in Poughkeepsie and one in Syracuse. If you're way up North there's a group in Ottawa, Ontario and another in Burlington, VT.
There was a group in Rochester a few years back, and I think they're still active (Rochester Medieval Longsword Club). There's also a rapier group in Ithaca and another group in Ithaca that I'm not sure what they're doing.

Edit: Just saw you listed your location as Rochester. Please tell me you're at the UofR (class of 2001
