I've gone the last few years. Really a fun event. Hospitality and food are absolutely fantastic. Targets are excellent (the 2013 US Open will be held there) and unique (one station bounced targets off a trampoline). The Parker Collectors are having their national meeting there this year, which should up attendance. Hunting for birds and deer are available on the property during the event. I believe a pheasant tower shoot is also available if a group signs up in advance. It's an hour away from Myrtle Beach if you want to add some beach time or golf to the trip.
