Free Sailing Open House Saturday 1:00-5:00 PM
No sailing knowledge necessary, just duck when your captain yells the boom is coming. Probably one of the coolest places to sail is the Boston Harbor and one of the coolest ways to do it is for free.
Free Beer, BBQ and Wine Saturday 1:00-3:00 PM
It's a bit of a track out to Lexington, but check out the free sample spread these guys will have: pulled pork, mini hog wings, corn bread, Tempranillo, Chardonnay, fancy cheese, Cape Cod potato chips, Ommegang ale, Brooklyn beer, Pretty Things and Cisco brewery.
Somerville Porchfest Saturday 12:00-6:00 PM
I'm amazed Jamaica Plain didn't think of this first, but here they are. 75 Somerville bohemians will be on their porch playing music for free all afternoon.
JP Springroll Sunday10:00-1:00 PM
JP'ers love their parades. I was woken up the other week by about 100 kids and some firetrucks marching down the street to kick-off softball season. This round we'll be decorating our bikes and rolling around the neighborhood
Earthfest Saturday 11:30-5:00 PM
Boston's Earthfest generally has little to do with the Earth. In fact, it creates quite a lot trash, but lineup seems good: Ok Go, some guy from Live, samples from Whole Foods.
