Shrieks waft through the sprays of water at Hayes Park on 1516 N Lincoln St. at the Friday opening of the Sprayground season in Arlington. Hayes Park sprayground just opened for the summer an hour before and is already crowded with splashing, running (whoops, no running) children. Grace Luk is here for her second year. Her pool isn’t open yet and “it’s so hot.” Sixteen-month old Wren Kennedy just loves it … “but is freezing; look at him shiver.”

The four Arlington spraygrounds are open from Memorial Day weekend to Labor Day weekend. Other spraygrounds are located at Lyon Village Park at 1800 N Highland St., Virginia Highlands Park at 1600 South Hayes St. and Drew Park at 3514 22nd St. S.
