Guys-
He's riding at Sun Valley doing laps down Warm springs your stand up and relax form don't work there--you'll just turn into a human luge for 3240' vertical feet. Art- your a really strong rider, your father in law is just a wimpy turning, two planker. Sun Valley is the ultimate leg killer when it is that chalk we were riding on. Just remember that PBR are the best nurishment for a carvers legs so don't give them up.
adios
Jeff
