I think that there's a difference between actually *making* gas prices higher and having them soar for one reason or another. I remember the argument between soda and IGWT but, if I recall, that was when Magician changed servers or something and my response was deleted forever.

No one seemed to mind, of course.
I see absolutely nothing wrong with commuting on your bike if that's the decision that you've made, but there is no way I'm going to make that same decision, for a number or reasons... not all of them because I'm fat and lazy, but partially because of them. Even my friends who are training for the IronMan Triathalon don't ride their bikes to work everyday. Some days, yes. But not everyday. If it were up to me, I'd ride my horse to work... but that's another issue entirely.
Personal transportation needs to be more economically and environmentally friendly. I see that as a better answer than to tell everyone to ride their bikes, IMO. As Shampoo mentioned, public transportation is horribly inefficient and there is no way I can feasibly get to work from my house on the bus. Well, possibly, but it would take me three hours either way and I just don't have that kind of time.
More power to you, soda, for your ability to commute on your bike. I think more of us should think about running to the grocery store for milk on our bikes or just taking a walk instead of hopping in the car. But that's a far cry than the commute that I look at every morning.
