Can see why this thread's on the "back burner" the way gas prices are going. Paid $3.65/gal today and it's getting awfully painful. 
After gassing up I went to Walmart and they had a bunch of new 2011 bike models sitting out in front of the store. Schwinn has a pretty clever marketing gimmick and has signs on their bikes that says, "Doesn't Use Gas!".
I started thinking about it and for the price of 1 1/2 tanks of gas you can buy a half-decent new bike. But if I'm going to be carrying 100 lbs of groceries, in the front and rear baskets of a bike, I'm going to need some training wheels.
