Aye, ‘tis true – Professionals in the City has commandeered a pirate-themed party vessel for a three-hour Independence Day cruise on the Potomac, capped off by D.C.’s world-famous July 4th fireworks show. Lads and lasses will find plenty of treasure on board the Boomerang, like an included pizza dinner and a cash bar, along with two open-air decks, water cannons, party music and a dance floor. It’s a primo place to mix and mingle before settling in for your perfect view of the pyrotechnics.
