Hey Karl, like the great photos and the bear spray... I always tell me physics students to run downhill from a bear and zig-zag because they have so much inertia they can't change their direction.... now I will just tell them to whip out the acme bear spray can....
I was wondering more about the flint knapping, like the photos from Oregon, I think I recognize some camping spots.... do you think you will trust little kids to flint knap with Obsedian? I like the picture of the child doing it, I wonder if kids were responsible for this at early ages back then... or if it was a male only thing, any such thing as a left handed spear?
Great Photos, keep up the nice work, Michael Lampert Polartrec buddy.
