Ahoy, mateys! When the season fer swimmin' the briny deep's upon us, get ye down to Englewood, where the Jolly Roger flies o'er Pirates Cove. The City of Englewood water park, replete with three pools, debuted last summer to rave reviews by just about everyone, from the tots in swim diapers to swimmers with serious agendas, and no wonder: There are six lanes for lap swimmers, a lazy-river feature and a leisure pool with play islands, a super-soaking 750-gallon dump bucket (look out below, me buckos!), smoke-belching cannons, a spray park, slides and sound effects. Load up your towels, beach toys, sunscreen, flip-flops, peg legs and eye patches, and head for the pool. Opening day is May 28.
