Very cool, indeed.
Had an empl*yee who walked freshly plowed farm fields in Indiana and Illinois, looking for native artifacts. She had dozens (maybe hundreds) of arrow and spear points as well as tools (cutting, scraping, tanning, etc.), many dating back 10,000 years. One very interesting find was, apparently, a camp where native Americans worked on these items, discarding their "mistakes". What an insight into the nature of human beings! We have changed so little in all those years. Our level of possessions has changed, but not our overall outlook on life. W*rk before you play, defend your territory, don't be greedy, strive for perfection, teach your children well. These were the take away messages that the lady espoused about native Americans. I tend to believe her conclusions as I see those things here on this forum. YMMV
