On Tilghman Island, Tickler’s Crab Shack delivers the bare-bones, no-pretense crab shack experience that the island’s remote character demands — fresh blue crabs, cold beer, and the easy communal atmosphere of eating messy food with friendly strangers at picnic tables beside the water. Tilghman’s remoteness filters the crowd naturally; the people who make the drive are the ones who want the real thing. Tickler’s delivers it.
