If you're a golf fan, there's nothing close to the Masters. The majesty of the event and the physical beauty of the course, combined with the hospitality of the Georgia hosts, is indescribable. The course was literally built to host a golf tournament and is easily the most fan-friendly venue of any event I've ever attended. I attended the 2012 Masters, won by Bubba Watson in a playoff.
The Mid-Atlantic is a golf mecca and the Virginia/Maryland area has hosted its share of PGA events, including the AT&T National at Congressional, the Presidents Cup for several years at Robert Trent Jones Golf Club in Virginia, and the 1997 and 2011 U.S. Opens at Congressional. I've had the pleasure of playing at both RTJ and Congressional, as well as other former U.S. Open courses, Baltusrol (site of the 2016 PGA Championship), Oakmont (site of the 2016 U.S. Open) and Shinnecock (site of the 2018 U.S. Open).
