Gas Prices

My girlfriends and I use to joke about having to borrow the carts from grocery stores to wheel our groceries home because we someday may not be able to afford the gas to get to the store. We laughed when we first said it, but gas prices are getting so high that we may just have to start walking to the store. There has got to be a way to get around these gas prices. I was reading about alternatives to fuel and I think that I will try a gas reformulator and see if I can actually increase my miles per gallon.
