Here, just 65-odd miles downriver from the Washington Monument, is a good-time precinct known as the 'Las Vegas of the Potomac.' At dockside dens such as the Jackpot, Little Reno and Monte Carlo, ladies and gents dressed to the nines cash in at the slots, then sidle up to the bar to drop their winnings. Some tourists are swinging their shoes to the night's big band at the Joyland others stroll the boardwalk and take their chances on the games of Bentley's Amusement Pier.īut the epicenters of glitz and glam are the casinos. Martini-wielding jet-setters from Washington and Richmond have flown in on champagne seaplane flights. College kids have ferried down the river for wild evening escapades. Asummer night in Colonial Beach: The piers stretching into the Potomac pulse with activity.
