From what I can discover, this hat is from a now defunct Resort that was on/around Grand Lake of the Cherokees in Grove, OK. I don't 100% know if the Peninsula was just closed or if it became the "Regatta" or some other Resort. PLEASE if you know the provenance of this hat or history of the Resort, let us know! Either way you slice it you can't go out and get any more of these Titleist golf hats. So if you collect hats, golf memorabilia, Titleist stuff or just live in Grove this hat is a great find! As you can see from the pictures it's in really good condition. It's black and adjustable to about any head size. We accept quite a few offers, so please offer! Check out the rest of our stuff too, we have nearly 400 items for sale on fbmp under PHAP THIEN so look around!!! We are grateful for your time.
