That sounds like 1010 for us - a local community college has a "professor" (you'll see what I use that term loosely for him) who has been teaching 'arrowhead collecting and identification' (can't remember the exact class name) for about 20 years.
He's been telling his students to go to the same site for 20 years for field collection.
When we were there excavating we kept getting students coming up, telling us about all the awesome things they had found over the years.
We found diddly squat in comparison.
GROWWWLLL!
ANother snake that's bigger? EEP.
