Yes, there is a Rochester, NY group! It's held every Thursday night at 7:00 - 9:30 pm at Rochester Makerspace. Info is here: www.rochestermakerspace.org
-- there's a link to the eventbrite calendar, but you can ignore it. You don't need to register, you can just drop in. We're also looking for participants in a Pi Day "show and tell" on March 14. Send an email to rocmakers-at-gmail-dot-com if you're interested.
