I used to hunt on a lease near Fredericksburg Texas that the guys called Arrowhead University. The cabin was on a rise over looking a valley, with a river about 100 yds out. There were tons of flakes around the cabin, so we speculated that the Indians must have camped there, too, and made their arrowheads there. The guys that had been on the lease for awhile had quite a few points to show. The only one I ever found had the tip and one of the barbs broken off, but you could definitely tell it was an arrowhead. Still have it in my curio cabinet.
