CUMMING -- Looking for some rootin’ tootin’ family fun this summer? Set your sights on the Cumming Playhouse as “Annie Get Your Gun” hits the stage for a four-week run. The show, which opened Thursday and concludes Aug. 2, tells a fictionalized version of a portion of the life of sharpshooter Annie Oakley (1860-1926), who starred in Buffalo Bill’s Wild West show.
