As of 3pm this afternoon, I have professional modeling experience. No SI centerfold or Men's Health cover shot, but you'll come across my mug somewhere within the August issue of Bicycling.
I was suprised at how awkward the whole thing was. Being the focal point is not my thing. Lighting sensors, flash bulbs, light reflecting panels, and cases of lenses. I faked pain faces, I lathered up with tanning oil, and I flexed so much it hurt. It was terribly unnatural at first, but when a guy's laying out of the side of a mini-van cruising at 30-35 mph with a camera a few inches from your front wheel, its hard not to feel a little rockstar-ish.
Bill, I know your checking this out, so thanks for the referral.
