Riders On The Storm. This is one of my favourite on the road shots taken on my way up to the 50th Sturgis back in 1990. Four Corners is in the middle of Wyoming and the riders are about to cross Thunder Basin and encounter a hail storm which left the pavement inches deep in ice in August.
I uploaded this scene once before but it was from an inferior scan that a book company had done before very kindly LOSING the original transparency. I just today found another slightly different frame shot at the same time which I have scanned myself.
