By the way, I did a little knapping/flint collecting on Friday night and Saturday before I left. The other hunters were very interested in the process of making points. I did these 3, gave them all away to the landowner, hog forum owner and a friend:
I was near Temple, TX. and found all this flint in the driveway of the farmer where we were hog hunting. None of the cobbles are big enough to be more than a single point. Most are buttery brown colored. I took a scredriver and was prying it out of the driveway when the wife called. Here's the first few I found:
and here's what I went home with:
I wish I could have found more of that dark gray stuff. It looked like georgetown to me and knapped nicely raw. I tried making a point with the brown stuff while I was there and it flakes OK but is very hard. Once I come up with a way of heating some I'll try again.
