Upon crossing the threshold at United Skates of America, a barrage of shimmering lights and colors assault the senses. A disco ball scatters rainbow shards of light across metallic streamers and low barriers striped with colorful lights. A glossy wooden rink acts as the centerpiece of the whimsical decor, packed with roller skaters during public hours. The vibe of open sessions evolves throughout the week in stride with rotating jams, from Top 40 hits to the hip-hop and R & B of the '80s and '90s. There are supportive Skate Mates, whom kids can grab hold of as they skate round the rink. Novice rollers glide like pros after skating lessons, held in five-week sessions by a team of veteran rollers, and partygoers zoom around the oval track during birthday bashes. An arcade and roller café offer safe haven for the athletically averse or those still mastering bipedality.
