Want to come on a bike ride with me to celebrate my birthday? The morning of May 14, we'll leave my house in Somerville around 10am, and ride 41 miles, to Lincoln, Concord, and Carlisle. We'll take it easy, and also stop for lunch in Concord Center (really this time). Total ride time will probably be 5 hours or so.
Also, I'm considering a range of insane bike rides for June. Do you live in North America but more than 50 miles from Boston? Would you put up a crazy cyclist for a night? Do you know anyone else who fits that description? Let me know. This username at gmail works fine.
