^^^^^^^ yes it's legal, however, keep in mind the definition of hunting, i.e., in pursuit of. So in short, yes you want to take every precaution you can. Assuming that your rifle hunting, I would keep my ammo and bolt in my pack on the way in, and on the way out. I would also completely ignore all animals on my way in and out, so as I give no impression of being "in pursuit of". I would go as far as calling the warden for that area, informing him of your intentions, and precautions, and ask if he would like you to do anything else so as to not be confused for a person trying to hunt both zones. When I am hunting areas of confusion, such as this, and near private property, I also leave my GPS on tracks mode every single day I hunt, and have it automatically store the tracks for each day. That way if there are any questions of where I was, I have digitally stored evidence of where I was, the time I was there, and for how long. I've ran into wardens a few times in such questionable areas and have offered up my GPS data for their viewing. Not one has yet bothered to look at it, and it has set them at ease that I am not there to break the rules.
I think making it clear to any warden (their perception) that although the possibility of breaking the rules is there, you are clearly taking every reasonable precaution to exhibit and demonstrate that not only that, that is not your intent, the tracks storing within your GPS provides evidence that you could not have harvested an animal illegally, in that you didn't spend enough time in any one place to make an illegal harvest, gut, skin, quarter, de-bone any animal you have with you. I also take pictures of every animal I harvest at the kill site. If it is an area of any question, I take pictures with my GPS so the picture is embedded with the coordinates. It might sound like a lot to do, but it's pretty easy to do.
I hunt pigs in one particular area that borders private property. A place where the warden has issued lots of citations. I've used the above method and have yet to have any issues with the warden or the land owner, and I have run into them both several times. But I do go to extra lengths to make it completely clear that I am doing everything in a legal manner. I do carry a large LION battery to recharge my devices; and if you do this, keep in mind that once you have fully recharged anything, do not leave them plugged into the charging battery, as it will continue to deplete it.
