We are having fun killing deer with the culling. If we hadn't already meddled than we wouldn't need to kill the deer. OK? But we did meddle, and we can kill deer now, while keeping the environment pretty decent, why not? And why reintroduce predators that will kill livestock, have the potential to harm humans, to kill pets, and so on, when humans can do the job, and do it without anyone actually paying money to have it done? How about "we can kill deer for fun, and it doesn't hurt the environment, so why not?" I don't think it's the cars that the deer will hurt must if their population grows out of check. Secondly, those devices do not always work.I also have serious doubts about the line we've been fed from the DNR on this issue.
There are cheap devices we can put on each and every car that scare deer away.
