Well...I can't say about deer conditions in Ohio, but the population is plentiful around here. According to a person I know at our state DOT the annual road kill is about twice what the hunting numbers are. I don't like the critters because they are a terrible hazard to navigation. You should see what a deer can do to the front end of a flat nosed school bus. I have. I don't know haw many thousands of dollars of damage were done, (a bunch!) but I suspect the driver was more than a little spooked when a buck deer tried to jump into the cockpit with him. Moose strikes are the leading cause of accidental death in Alaska. I know a guy who used to drive school bus in Alaska and he said that the only time it was permissible to put a school bus into a ditch (without getting fired, that is) was to avoid a moose strike. I believe him.
I've been lucky, the biggest thing I've hit was an immature turkey. (An introduced species.) The business across the alley from me is a body and fender shop who employs 4 or 5 guys doing mostly repair work to cars that have had deer collisions. The proprietor of the body and fender shop lives in a nice house and drives a nice car due to the profitability of deer strike repairs.
And don't get me started on introduced non-native species! I know a farmer who has special permits to kill elk because they are destroying his crops. The Roosevelt Elk is an introduced species which seems to be on the decline around here, due primarily to predation by wolves, another introduced non-native species.
I can go on, but that is more than sufficient.
