Get outside and give back. Be a part of an ongoing volunteer effort to maintain the heavily-used Resthouse Meadows Trail, which ambles through open, wildflower-strewn meadows. Volunteers for Outdoor Colorado continues the effort this year with a project to replace an old bridge that has seen better days. As the work site is remote, volunteers are asked to sign up for the entire backcountry project. Learn more and register at www.voc.org/projects or call 303-715-1010. Free to participate; no experience necessary; minimum age: 18. Camping provided.
