It's not simple to not fill up when you have a 20 mile commute every morning. If I rode my bike to work, it'd take me hours! xD I don't live right in NYC, where I can take the subway. I live out in the 'burbs where you have to drive everywhere.

Sorry, it just bugs me when people who don't drive or have cars say that it's so "simple" not to have one. I can't have mommy drive me around for the rest of my life.

I recycle though. When it's an nearby place, I walk, but more for my own health than anything else.
