Dew Tour at Lauridsen Skate Park Des Moines' long-awaited, 88,000-square-foot Lauridsen Skate Park is scheduled to open this month, and it's starting with a bang. The Dew Tour, an annual skateboarding competition and the only U.S.-based global Olympic qualifying event ahead of the summer Olympic Games in Tokyo, will hold competitions in Des Moines May 20-23. Over 300 professional skaters will compete in the four-day event. While all tickets have been claimed, the competitions will be livestreamed at DewTour.com and on Facebook Live and YouTube. The tour is expected to generate at least $4 million for the local economy.
