Im saying range is a fluid thing, Im questioning what point in time is the goal post. There is a ton of research coming out that the perception that the US was just this open wildland with occasional Indian tribes is incorrect. Pre Columbus and Pre small pox the US population was higher than Europe. Effectively, the tribal situation we think of was North America after an apocalypse. They are figuring out there were much larger communities and cities here. They also terraformed the landscape, clearing a lot of trees, forest size expanded significantly the few hundred years after Columbus dropped off small pox. The whole environment changed. If this is all true, you can't find an environmental state that is untouched by humans and you are creating an ideal state in your head. Thats like saying dinosaurs should have all this territory still because at some point in time removed from all context they were in this spot.
Example below from a quick google search, interesting reading even outside of this discussion. There are books dedicated to the subject. Ignore the sensationalized anti European title.
The diseases brought to North America by Columbus and other colonizers killed 90% of indigenous populations, sparking a global cooling.

Now, back to the overall discussion. I think I feel a bit better about being outdoors with grizzlies hearing from a lot of you from Montana etc. Still on the fence on the expansion. I was a kid in rattlesnake country and it seems similiar to rattlesnakes to me. I don't worry about them. I subconsciously follow certain rules I learned growing up such as watch where you step, don't go blasting through tall grass, avoid holes and other things that look "snakey" don't stick your hands in places you can't see, etc.
