So the sked is in for the Mass. Climate Summer bike tours, and they're skirting Arlington, though that doesn't mean we can't get in on the fun.

They'll be in Lexington July 21-24, Waltham July 24-27, and Newton July 27-30. 

If you want to offer a place to sleep while they're around, you can e-mail here. The entire sked is at massclimatesummer.org. If you want to host an event, or participate in one, go here.
