Take a trip back to Tudor England at this annual royal affair. At opening weekend, kids 15 and under admitted free. Perhaps you’ll meet King Henry VIII, Catherine of Aragon and their royal court in Revel Grove. Eat giant turkey legs, see jousting knights, juggling fools and lovely ladies-in-waiting. It’s even more fun when you come in costume — or rent at the fair. 10am-7pm SaSu, 1821 Crownsville Rd., $19 w/discounts: rennfest.com.
