I love the fact that "I'm my own engine." In fact, I have that written on the bottom line of my Road ID bracelet.
About a year ago I posted on Facebook what I thought were the benefits of cycle commuting. Of course the only people enthusiastic about my post were other cyclists. By memory, some of the benefits I really enjoy are that I feel further connected to my community greeting other people & smelling the local smells, being green by not burning gas, getting an efficient workout twice a day and feeling refreshed when I get to work. I also like some of the interaction with drivers-- some. Of course there are drivers who lack respect for us cyclists, but when someone does give me the right of way (even if I was supposed to have it) I will give them a thank you wave. It just makes me feel good, doing that.
