Here in KY, we went to not even having to attach a physical tag unless it leaves your possesion (i.e. Processor, Giveing it to someone, Taxidermist, Hauling in someone elses vehicle, etc..). We do have to fill out a harvest log on the back of our hunting license or deer permit before we move the animal though. Our deer permits entitle you to 2 deer, either one antlered and one antlerless or 2 antlerless deer. We can then purchase Bonus tags which is for 2 antlerless deer. When we harvest a deer we just have to phone it in on and automated check in line. And fill out a harvest log with a confirmation # that is given at the time of the call.
I wish that we did still have the mandatory phyisical tags because I believe that it keeps someone honest. I have talked to people that have been able to slip by and not tag an animal and take more than their allowed. Seems to me that is unfair, and obviously unlawful.
Allbeit, in the "zone" that I hunt in we can continue to buy as many bonus tags as we would like, but some I guess can't seem to just put up the extra $20 for them.
