From 10-2 on Saturday, green partisans will gather at Somerville High School for demonstrations, giveaways, and fellowship with their own kind.

Byggmeister, the Newton energy efficiency buidling contractor, will have a representative to evaluate your energy bills for what you might save, there'll be recycled kids crafts and recycled fashions (and you can bring clothing donations to do some recycling yourself), free basic bike tune-ups for people who ride over, and plenty more.

The event is free; maybe I'll see you there.
