Dumfries Golf CoursesPotomac Shores Golf Club, an upscale public course in Dumfries, Va., is set on rolling, forested hills on the banks of the Potomac. Almost every hole on this Jack Nicklaus design is encircled by dense forest, and very few holes are very flat. Most tee shots feature beautiful, elevated vantage points. Greens are large and undulating, so precision on approach shots is the key here.Jack Nicklaus' opening tee shot this week at Potomac Shores G.C. in Dumfries, Virginia came about seven years later than it was supposed to. Revived by SunCal and managed by Troon Golf, hilly Potomac Shores is the only public-access Nicklaus Signature design in the Beltway.
