Well, some of the last three apply, but not the real reason I started riding.
My family had a quadrunner when I was in high school, but other than peddle bikes I'd never been uo2 before. Shortly after college I had a relationship with this idiot. He moved in, and talked me into buying a bike. I've always held equal amounts of fascination and fear of bikes. I only rode with him twice (totally afraid and not riding properly) before the relationship ended and he left me with bike payments and a bike I couldn't ride. I sold that one; but now years later (still equally intimidated and fascinated by bikes) I decided enough was enough, I signed up for the MSF course and bought a bike. I won't live in fear of anything, and the only way to deal with this one is to get comfortable on the bike. So now I ride.... Sometimes I'm still all nerves, and sometimes I just feel the bike.
