I don't know the exact details. I have talked to a number of people who are intimately involved, from street level law enforcement to the Cornell Biologist in charge of the neighboring hunting and sterilization research project (even sat through his little informational seminars for hunters), as well as a few (reasonable) people who live in Cayuga Heights. I only know that every conceivable method has been proposed and/or tried. They proposed the sniper thing, the capture and relocate thing, the bowhunting only thing, the sterilization thing.....
The major problem, but by far not the only one, is Cayugadeer.org. The organization is run (or at least funded) by Mrs. Parks, who made her fortune via Park Outdoors, a billboard company. She lives there and is among the more radical of the radicals.
They oppose every effort, except the ineffective ones like sterilization. Bowhunting, it seems, is especially dangerous to peoples pets, and children even.
Frankly, the area is 1.8 square miles, according to wikipedia. I doubt it's big enough that anybody on the state level could give half a rodents rear-end. Nobody goes there except those who live there and it doesn't really cause problems for anybody but them so, in the end, who cares?
Well, except those hunters among us who see the 175-inch class, 8 1/2 year old, 14 point standing there on the side of the road. We care.
