In the past (Jettrim Vintage Museum 2011) we met Clayton Jacobson III, son of the inventor, Clayton Jacobson II, who plans to come over at Jettrims Vintage Museum and meet the people who are interested to find some more about the roots of this sport. He will also be selling his autobiography, for $49.99. So if you want to buy a personally signed copy of his book you know where you have to be on Pro Saturday. This is the true show of this years World Finals. Do not miss it. Clayton Jacobson III pictured at Jettrim's Vintage Museum in 2011.
