Mercerdale Park is hopping with activity. Not only is there the popular Mostly Music in the Park concert series currently running, but this Saturday, July 28th, is the first Free! Free! Free! Family Movie. The scheduled movie is Steven Spielberg’s E.T. The Extra Terrestrial, in celebration of its 30th anniversary — although you don’t look a day over 28, E.T. =). The movie is rated PG and runs approximately 115 minutes. Parks and Recreation staff will be at Mercerdale Park for special activities inspired by the movie. Activities kick off at 7:30pm and E.T. will start about 8:30pm.
