They have damage hunts in Montana for deer and now elk, but the landowner has to show toll free access or at least a willingness to help out. They used to have it as a tag that was drawn lottery style. But some people were getting ripped off. Now they let the landowner choose who they grant access to, but there is no charge for access during a damage hunt. You should see what 600 head of elk can do to a hay stackyard.
Some of the large dude ranch spreads have thier land all locked up so the elk population is really high on those places. Thing is they don't own the elk or deer, state of Montana owns all the game. We get bad weather in the hunting season and those big elk herds will spin off in all directions. Consequently the hunting for these animals in MT is pretty good because of those ranches. They feed em and shelter em most of the year and then we get to hunt them when they get on the ajacent lands.
I guess if the problem in TX gets big enough the landowners will have to cave in and let you guys hunt the hogs.
