Join the Red Line Parkway Initiative on Saturday, March 7 for the Spring 2026 It's My Park Day! We'll meet at 9am on the Boggy Creek Greenbelt Trail just behind the Downs Mabson Fields, and mulch nearby trees along the trail. Mulch feeds trees as it decomposes and helps protect them during the hot summer months, so that they can keep growing and providing much needed shade for years to come.
