Hey all, check out our new bookstore at
http://www.bikeportland.org/books for a bunch of biking and planning book ideas.
Besides being a resource for books you might like, our bookstore is also a portal to Powell's, with whom we have a partnership -- every book, movie, t-shirt, etc you buy (even ones not in our bookstore) during a visit to the Powell's web site that originates from our links earns us a commission that will go straight to helping us improve BikePortland's content and features.
By the way, I'm adding every book I see discussed here to a list for possible future inclusion, so keep the ideas coming! And feel free to get in touch personally if you have any suggestions.
