CANCELED DUE TO CONSTRUCTION.  Explore in carpools this now-closed landfill adjacent to the Blue Mash Nature Trail. Mostly open terrain on a gravel road, including two pond views. In addition to sparrows, raptors, and waterfowl, shorebirds are possible if there are mudflats at the big pond. The leader will have a scope for distant birds. Limit: 16. We will start at 8 a.m. For reservations (required), contact the LEADER: Mark England at [email protected] or 240-308-4114.
