This 4th of July, I’m headed a few hours north of wine country (Napa Valley, for those of you not familiar with NorCal) with a few buddies of mine to do it up in a lake house. While on the lake, we’ll be engaged in tons of water sports, so I decided to do a little bit of research. In my quest for knowledge, I came cross the video below about folks bored with wakeboarding in a lake behind a boat. They seem to have decided it was time to head down to thier swift-moving neighborhood creek, attach the same type of motorized, ariel tow lines they use in wakeskating, and wake upstream against the current. The footage is from last week’s 2011 Red Bull UpStream in Slovakia’s Bratislava, Cunovo. I’ve never heard of any of the winners of this bizarre, foreign water sport, but it looks quite, quite fun none the less.
