Nearly a year after the PGA Tour Superstore opened its doors at White Flint Plaza, a second golf store is swinging into Rockville. Say hello to Golfdom — a fixture in Tysons for the past 40 years, now open in the former Pier 1 space at Pike Center. Employees promise “more of a boutique experience” than the massive PGA store, with a smaller but robust selection of equipment, golf clothes and simulators, as well as custom fitting services and repairs.
