Looking for something to do Friday afternoon? Enjoy the summer -- and feel groovy -- at an outdoor concert at Planting Fields Arboretum in Oyster Bay. Shenole Latimer, an innovative progressive jazz saxophonist, is performing on the Haybarn Lawn from 4 p.m. - 6 p.m. Bring a lawn chair or blanket and a picnic basket. While you're there, poke around the 400+ acres of serene gardens and check out the newly renovated Italian Garden. The concert is free with admission to the park ($8 per vehicle). Call 516-922-8600 for more details.
