A colleague at work just bought his own customized Timbuk2 bag. The bag he made is incredibly cool, as he was able to customize the interior and the exterior of the bag, making it unique to his personality. The coolest thing besides the customized bag was the very innovative and unique plastic bag that was carrying the Timbuk2 bag. (Yeah, I know, I've used the word "bag" alot).
The plastic bag isn't meant to be thrown away, because it is a bike map for the city of San Francisco, complete with an elevation table, routes, and Timbuk2 store locations.
