I figured out how I can buy a new bike for free! (at least it's free in my own little twisted mind..)

A friend of mine suggested this to me yesterday. I just started bike-commuting to work last week. I've been keeping track of all my riding miles on bikejournal.com. I'm going to aggregate my commuting miles, and every time my commuting miles adds up to the distance I can go on 1 tank of gas in my car, I'm going to put 1 tank of gas worth of money aside. i.e. - My car will go about 300 miles 1 full tank of gas, and a full tank of gas costs about 20-25 dollars right now. So, every 300 miles of commuting, i set aside $23 dollars toward my new bike! After a while, I'll have enough for the new bike, and it'll basically be free, since I would not have had the money if I had still been driving to work! WooHoo!!
