Hey All,
Check out this month's issue of RacerX. It has a picture on the cover and a related article of DiStefano and Wienert. Some great MX action and history of the day!
Ed Youngblood posted an article on this along with a copy of the picture on his "News and Views" page (about half way down) called "The Best MX Photo Ever? - 1/8/2004. The picture definitely rocks!
