I should mention that Boulder, CO is determined to beat us to the first Platinum city. They have something like 14% of all trips made by bicycle already, while Portland (depending on how/when/where you count) has something around 5%. That's going to be our biggest challenge, and one that will bring with it greater rewards than Platinum desgination if--or rather, when--we succeed: getting more people on bikes, more of the time.

Readers, I challenge you: what trips do you make now by car that you could make by bike? How about making that change for just one trip in the coming week? Could you keep doing it? If everyone in Portland committed to even just one trip by bike instead of car per week, we'd really get somewhere.
