If you're looking for some serious fun, you may want to think about finding yourself a bike and joining the Green Train at 12noon at Gulou this upcoming Saturday.

It's probably the bike ride you always wanted to take, but never had anyone who wanted to take it with you:  a bike ride from Gulou Drum & Bell Towers all the way to the National History Museum.  It's wide open in terms of inviting friends.  They have a goal of making 350 riders – I'm curious to see if they'll be able to pull it off.  http://www.350.org/BeijingGreenTrain  If you want to learn more and/or RSVP.
