he talks about it here:
You also had your classic TWS cover in Jan. 2004. One of my all time favorite covers. Can you break down shooting that one? Did you know it would be a cover?
Well, the night before that photo was shot I had been out all night partying--how you do in Spain when you first arrive. The next day Kenny (Reed) was going skating with a group of people and meeting up at Sants to go skating with Pete Thompson. This was something I rarely did--go skate in an organized manner. Anyways, I went to Sants with Kenny, Paul Shier, Jack Curtain, Quentin de Breiy, and Justin Strubing. I was pretty out of it and Sants wasn't really my scene. I was about to just skate and sneak off and go back to center. Right as I was creeping away Pete shows up with his roller bag. So Kenny says, "Just come and skate." So we took off skating in a part of the city we had never been and all sudden those silver roller humps appeared. I followed Justin down the street and kept going off them and eventually by the time we got to the next spot--I really figured out how to fly off those things. We went to some other spot to check it out, then Pete asked if I wanted to go back and try and shoot a photo. So we did.
That was my first six months in Spain and only the second photo I had taken in the six months I had been there. Also the first photo I ever shot with Pete. He was shooting for the photo issue and that was the last day to shoot for it. That was mid October and on my birthday three weeks later we were at dinner on November 7 and Justin just handed me the magazine. I got the cover with that photo. Had no idea. That photo saved my career for about four more years.
