Awesome Jr Masters slalom from the guys!! #nautiquemasters

@TheDanotmano Any chance you can get someone to update the masters website with results?? Would be nice to know who won men's tricks.

Got to catch up with Keith Lindemulder from Nucor. Great to see USGBC North Texas represented at Earth Day Texas!
