Found a bunch through the years, on the farm I grew up on in east Alabama, and find them here from time to time, working their way up out of the ground, or on gravel bars in the creek.
I've played around with flintknapping, and the crappy stone that those east Alabama Indians had to work with is horrendous... it's amazing to me that they ever managed to make something that could poke a hole in anything with that old amorphous quartz and quartzite rock - but I found some nice points made from stuff that was non-native, so they must have been trading for better material from time to time. I'm currently located close to a neolithic quarry of 'Dover Brown' chert, and nodules of 'Kentucky Blue' chert often show up in quarry spalls from the limestone quarries in the area. I find points made of both blue and brown chert here.
Here's one I found in a wildlife food plot at what was probably an Indian campsite that I plowed & planted when I was 15... found the bottom half then, but the tip piece appeared 35 years later when I plowed it up so my kids could hunt for points and pottery shards. It's not native to that area, and as soon as my son came up with it, I knew exactly what it was...
