We've had a group of LARPers gather to the right side of 16's fairway (Dolese, OKC) for the past month or so. Most of them decked out in their costumes complete with foam swords and shields. It's quite amusing watching them acting like they've lost limbs and still try to fight. It reminded me of the Black Knight of Python fame.
We have larpers at a local course. They know where the disc golf is and use an area out of our way. So we tend to all get along. They'll tell you all about what their doing, and will listen to disc golf stuff.
Went to Cameron Park in Waco, and there was a huge larping thing going on. It was insane. They had guys with swords, javelins, pikes, and even archers. And something like forty out there at a time.
