As part of the Hampstead Conservation Commission’s Outside in Hampstead series, Linda Ross will host a hike June 7 to the Blue Heron Rookery. Hikers will pass the covered bridge featured on the cover of Hampstead’s 2014 Town Report and go on to the rookery. Bring waterproof boots, bug/tick spray, hiking stick, binoculars, and a camera if you like. The hike will begin at 1 p.m. and take about an hour and a half, leaving from the Golden Meadow cul-de-sac in Hampstead. For more information, contact Linda at LMGRoss49@yahoo.com.
