I'm starting to use my bike to commute and for errand running, groceries etc. I keep my bike in the garage, but I can't take it through my living room because we have a light colored carpet. I keep thinking how great biking is for the our non-dependence on fossil fuels. Yet, everytime I take my bike out, I feel guilty about using the electric garage door opener to get it out. <sigh>
I'm not sure how much electricity that consumes, but it's gotta be a lot. It probably takes a lot of juice to power that thing. Twice!
