The Makers Faire is in San Mateo, CA this weekend (May 21-22). Considering the amount of DYI and "making" we have to do to maintain mopeds it seems like a venue that alot of MA people would appreciate. Mike Rowe (Dirty Jobs) will be there Sunday.
My wife and I am going (coming from Sacramento), will be there both days, not bringing a moped though. (edited)
