I don't know what type/series of race it was. It was happening on my local reservoir just one entrance down from my dog park so I thought it might be fun to watch. Took my dog too - he slept between the legs of the tripod.
I've taken my boats here to over 50 mph and, because it is such a high traffic lake, all the boat wake really takes a toll on the body & gear. I can't imagine the abuse these drivers were taking.
