Gear Works Cyclery in Leominster MA is doing their annual thing. They collect a bunch of 'pre-owned' kids' bikes, spruce them up, and then they're distributed to kids that might not have a bike otherwise. Next Tues and Wed, 12-11+12, they're hosting wrenching sessions, where a bunch of volunteers hoist a few and do their best to turn lead into gold.

If you're local and turn a wrench now and then (or even wield a mean wipe-down rag), it's pretty rewarding. I'm planning on going Tuesday.
