Levi even mentions the guy on his cyclingnews.com diary:
July 21, 2005
Levi Leipheimer (Gerolsteiner)
Guess what today's stage was like? You guessed it! Fast and hard. Not to mention really hot. So hot that one guy had to take all of his clothes off to cool down. Not a racer thankfully, a fan.
If you watched the coverage maybe you saw him running with us. You just never know what you're going to see at the tour. You do know that you're going to see a lot of people acting crazy on the side of the road - but naked? <snip>
