Mark your calendars. Saturday, June 2, 2012 is National Trails Day this year. A good day to tell someone you love to "take a hike!" Or, a good day to find a volunteer opportunity and help build, maintain, or clean up a trail dear to you.
One place (among many) you can go to volunteer today is Radnor Lake State Natural Area. Check with the office at Radnor or at REI for details.
