deer in town

Three deer have found their way to a park in Manhattan.  Residents are surprised to see them and wonder how they got on the island.  Some say that perhaps they took a swim to get there.  They've ventured outside the park looking for food and water but quickly return.  Some residents have left water for them and the deer are eating from the shrubbery. Rangers are monitoring the deer but under the law, cannot relocate them.  visitors to Harlem
