It's free admission all weekend, making it the perfect opportunity to check out the museum's inaugural exhibition, Andrew Wyeth: Memory & Magic. Live music, art-making activities and much more round out the fanfare. See cover story. Free. Sat., 10 a.m.--midnight; Sun., 10 a.m.-- 8 p.m. 1280 Peachtree St. 404-577-HIGH. www.high.org.
