I had quite a collection as a kid....mostly the same sort of artifacts as you, Xerxese....arrow heads in various stages of finishing, and a few celt heads.
I grew up near a spot that had 3 converging creeks with several "high spots" at the area where they ran together. Used to hit that high spot every Spring when the farmer would till the area and find a few good pieces.
I found several good spots like that.....almost had to think like the Indians,,,,,,making their tools where they could overlook valleys, streams, and other geographic features that made sense where good hunting would be.
Thanks for bringing back those memories....damn near forgot them!
