Most of these finds have been right on the edge of a creek, and most of them were found were a drainage ditch was dug to flow into the creek.  I also found a couple of points and a mano in a rock wall that was built behind some houses.  It looks like the rock wall was constructed when they were clearing the land for the houses.  I have also found quite a few preforms.  Let me know what you think of them. 

Thanks again.
