This summer, forgo the luggage, gas and headaches that dampen the usual trip to the beach and enjoy only the best parts of vacation – sand, cool water and beer – right here at the annual DECATUR BEACH PARTY, a fun-in-the-sun celebration. The Decatur Business Association ships in 60 tons of sand to transform its landlocked square into a coastal oasis complete with wading pools and a newly expanded boardwalk. Slather on the sunscreen, build the ultimate sand castle and fill up on funnel cakes before heading over to the MARTA Decatur Station plaza to complete the evening with tunes from the Reputations and Terry Lee and the G.T.'s. Free-$10. 5 p.m.-midnight. Downtown Decatur. 678-553-6573. www.decaturdba.com.
