Many years ago we never saw deer. Ohio has deer hunting during November and December, when it first gets cold.
Hunters go out in the woods to shoot them. Now, it was 2006, 2005 ish, at the industrial park, between two clear city buildings, asphalt, mowed grass, on a trip to the dumpster someone came across about a dozen deer, in the, well it's a lawn, between two city buildings nowhere near the trees.
I surmised, that somewhere along in the generations, some deer <(plural) learned that Elmer Fudd isn't shooting at them in the city, because police frown on discharge of a firearm in city limits.
but the deer that stay in the woods, they all got shot by Elmer Fudd over 100 generations.
All the deer that are left, are the offspring of the ones that were stupid enough to hang out in parking lots 30 some years ago.
It's like all the deer you see, are the offspring of the (akin to) the kids who would hang out in goth makeup and smoke weed behind the school building during high school.
It's akin to all of human society being eliminated except for the ones who became clown posse jugalos and wore makeup and followed a band around as groupies,
over 30 generations, all of the regular, well adjusted forest dwelling deer have been killed by hunters, and there are no deer left except for the ones who hang out in parking lots during the winter months.
I saw a deer while driving, hugging the brick outside of a church building, from a 1/2 mile away, with it's movements, just a couple of years ago that reinforced this theory.
