I only checked out a part of platter, was by myself in the rain and didn't wanna get stuck. Not much really there, but bring a fishing pole or whatever and hang out on the lake shore. Could be fun. What's over in your area? Gainsville is just as close as platter is. Also, 89 miles from Sherman is Buck Creek/ Daisy, supposed to be great wheeling there. Looking to head that way in the fall probably.
