The problem is that our current road system doesn't really support a massive shift to people-powered transportation. Everything in this country is designed around getting people from Suburbia to commerce in as little time as possible.
We would have to see a massive shift with people starting to live in the communities that they work in, instead of getting a house 1/2 an hour drive from work. I wish it would happen, that's a world I would love to live in, where neighbors work together, take care of one another and even get healthy together. Sounds like Utopia!
The gas prices have officially shifted me into commuter mode now. I've started building up the beater bike. I already have to get up at 5 am to drive to work. I guess it will be 4:30 now so I can ride. I've been wanting to make the switch anyway.
