What Knott said, and ALSO, it's okay to put your right foot down first.

So do I. I know we're in the minority. Always have, probably always will. Bicis aren't "meant" to be dismounted one side or the other (unlike motos, which do require the right foot on the rear brake, and even after a 12 year hiatus from bicycling in which I rode tens of thousands of moto miles putting the left foot down, I still unclip right).

People say it's normal to put your non-dominant foot down first, but I'm right-handed and right-footed. What I am, though, is left-eyed (cross-dominant people are also in the minority), and I wonder if that's it. Think I'll post a poll....
