On Aug. 17, visitors to Sleeping Bear Dunes National Lakeshore can listen to eclectic bluegrass artist Mark Lavengood from 8 to 9 p.m. at the D. H. Day Campground amphitheater. The concert is part of the free Find Your Park Concert Series in celebration of the National Park Service (NPS) Centennial. Members of the Quest music program, led by Earthwork Music founder Seth Bernard, will be opening the show. Because of limited parking at D. H. Day Campground, visitors who are not camping will be asked to park in Glen Haven and hike or bike to the D. H. Day Campground amphitheater via the Sleeping Bear Heritage Trail.
