Uma made a sweet Instagram video of one of my favorite things: the pumptrack at the Lumberyard. JMD showing the kids how it's done on the pump track @lumberyardmtb—the best air conditioned activity in Portland! The 'yard is closed July 4th because 'Murika, Eff Yeah! But they'll be open to fuel—and cool—your pump track riding tomorrow. ;-) @jmdeldin #pumped #pumptrack #jumpline #jumpjam #ride #ridemore #mtb #bmx #happyplace #shredfilter #makeawesomehappen A video posted by Uma Kleppinger (@theumabomber) on Jul 4, 2015 at 12:34pm PDT
