My wife and I plus our grown children will be in McDonough for the wedding of my oldest nephew. My sister and her family (from Washington State) will also be there. Besides the wedding, we are also interested in just getting together in the afternoon on Sunday to let the cousins play frisbee and maybe just talk about old times. I have been looking at state parks but nothing seems to fit the criteria. Either too far away or not enough area to picnic and let the kids play with the frisbee. Any suggestions from my TripAdvisor family?
