I don't know what it is but I always play better alone then I do in a group and I'm not sure why. I can go out and shoot under on a given course and then go there for a random dubs or singles function and stink it up almost every time. After 17 years I've kind of learned to accept it but it still bugs me a little. If I had to guess Id say for what ever reason I loss that mental focus in a group and I'm not as sharp. Anybody else have that issue and if so what are some things you've done to overcome it?
