It's spring, the weather has been perfect and May (which starts Thursday) is Bike Month. Middle-aged folk like me (and Room 8's Larry Littlefield ) are looking for exercise, cheap transport and global warming solutions. Bike messengers, Critical Mass riders (like my Council Member Rosie Mendez), edgy fixed-gear fanatics and teens are already out there. Join us.

It's already too late to sign up for the biggest NYC pleasure ride the Five Boro Bike Tour on Sunday May 4 which filled up at the beginning of April. The 42-mile car-free ride through NYC's streets parks and highways is an odd mob scene with a cast of tens of thousands, lots of snacks, flat tires and sweat. Because the whole ride is done with no cars, you get a little of the feeling about what a car-free-NYC might be like. Pedaling on auto-free highways is a revelation. It is definitely not for those who want to be alone. If you're going, look for me there.

United For Peace & Justice , the anti-Iraq-War coalition, announces its second Pedal For Peace fund raising ride for Sunday, May 31, 2008. It starts at 11 AM at 110th Street & Adam Clayton Powell Blvd. in Central Park. Since it's a fund raiser, there's an entry fee (waived for those under 18). I went last year and liked it a lot. I'll be there this year too. Come say "Hi!" For more info Click here (pdf, sorry)
