I will bike to work on all of those days everyone has mentioned. For solidarity. (And so I can get to work.) No one's doing a bike to work day around here. The only one to do it is me and at some point I realized I can't organize everything. So I've picked 2 things-- the bike class, and a 4th of July bike ride that is part of the official city festivities. Hopefully momentum will pick up and in a few years we'll have Bike to Work Days and Bike Month and all that fun! In the meantime I'll vicariously enjoy yours.
