Except I ride my bike. I get in free. I don't ride when it rains, but it doesn't rain very much out here. In the ten years that I've been doing this, I've saved about 8 grand or so and my savings rate is accelerating. Granted, I live close enough and I don't have kids to pick up and I don't have to wear a suit, but still, I think it just doesn't occur to people that they can do this.
That may change. Every time there's a spike in gas prices I see more people in the bike lane. I really don't mind the prices going up, especially in the summer when I can ride every day. More people will ride and we'll use that much less oil. And have thighs of steel.
