In the fall peewee football reigns and the smell of popcorn wafts from the concession stand. In winter Latin-American and Haitian teams in brightly colored soccer jerseys take to the field while, on the basketball court, shirts and skins dribble, then dunk. Paths offer biking and skating, an old train locomotive encourages climbing, and ample shelter is available for the days that rain dampens an intimate picnic. At Holiday Park, which was recently renovated, Broward County's white-skirted seniors can find love at the Jimmy Evert Tennis Center; the homeless may unfurl their bedrolls at twilight and enjoy the park's 91.1 acres of respite. And when the downtown skyline is dusted in sunset and framed by green, even a plodding, obligatory jog becomes a holiday indeed.
