Spend your sunset building sweet singletrack with SDMB and Pima County. We'll meet at the 36th St. TH at 4PM and plan on working until dark. Bring work gloves, water, and an adult beverage or two. We'll provide the tools. If you want to join but can't make it at 4, we'll be working on the hillside just below the stone house. Questions? Email trailsteward@sdmb.org.
