More bikes and more/better bike infrastructure would help, sure, but...

One obvious thing that no one seems to be talking about (probably because it's even more politically dangerous to address) is changing agricultural policies, so that we're no longer producing mountains of cheap corn ready to be turned into cheap junk food. Might it not be better for our nations health if real food were cheaper than the junk? And if the crappy groceries in poor neighborhoods carried real food?

And it's so retro, but how about home-ec for all kids? If their parents don't cook, and their grandparents don't cook, they're not learning just how easy and cheap (if maybe time-consuming) it can be to put together a tasty, healthy meal... I recently took a loaf of home-made bread to a neighbor who's been having a rought time, and her 11 year old daughter had never even seen a loaf of home-made, not pre-sliced bread. Somehow, I don't think that's all that unique. There's something wrong with this situation...

Anyway, my 2 cents...
