I love bento! Both for the bike, and for my lunch.

I've been using all kinds of bento boxes pretty much my whole life. And now that I live in Seattle, they're *so* easy to find. But, they're completely addictive. (Just a friendly little warning.)

CA_in_NC, do you have any Asian grocery stores in your area? That's usually a sure place to find them. A little poking around online will reveal lots of resources for ordering.
