Ask HN: Any hacker meetups near Philadelphia?

Does anyone know of any periodic hacker meetings in or near Philadelphia? If none exist yet, let's organize one. We could meet, say, twice a month at a local Borders to discuss the projects we're working on, startups, technology, business, etc. Anything that would fly on HackerNews would fly at our meetings. If you're interested or have info on an existing one shoot me an email (see profile) and we'll go from there.
