I very recently bought a bicycle and a small back pack to carry stuff around in. Using it to go back and forth to market, post office, and other errands. I am getting much needed exercise and saving money on gasoline. At the current price of gas, (which will no doubt keep rising), I expect the money I am saving on fuel will fully pay for the cost of the bicycle in less than two months. Obviously cannot use it for all of my transportation needs, but I can use it for many.
