Boarders, bladers and bikers who've cruised through Sandstone Ranch Skate Park since it opened last June might take the 24,000-square-foot concrete course for granted. The smooth arrangement of the expert sections -- like the pool and flow course, alongside such street-plaza components as stairs, gaps and rails -- is so close to perfect that the layout seems obvious, as though it couldn't possibly have been done differently. But that's clearly not the case, as evidenced by the region's abundance of crappy, cramped ramp parks that were definitely done differently. Props to Longmont for entrusting the design to SITE Design Group, true artists of skatepark simplicity.
