OK so they can learn a lot about their captive herds in the enclosures using this system. I would think they already do that to study their animals and their DNA whatever. It still boils down to an eventual use of this system to get clients to pay for a photo for a trophy animal. I think the contest would be an infomercial for the guide/owner. I don't believe the DNR anywhere would allow this outside of game ranches. Deer need to be harvested annually to keep populations in check. I believe windwalker is probably correct in that these deer may become educated to the tranquilizers,but probably not. Many veterinary drugs have an amnesia effect, the reason some have been used as date-rape drugs. The way I see it this is just a way to make money for themselves,I'm against it but I don't see it going mainstream anytime soon, and I doubt anyone will ban hunting.
