Let's expand the question a bit.
I'm assuming we are talking public land, which is where I do almost all my hunting. That being the case I do not climb anyone elses stand but I also do not think if another hunter choses to that he is doing anything morally wrong.
I see it like this. We use portable stands almost exclusively. Carry them in and out every time. So imagine that I've found a spot and market a trail and then a few days later I carry my stand out there in the dark and climb my chosen tree. Suppose also that someone else has set up a permoinant stand very close to me and I have not seen it. In the thick woods here in Flroida this does happen.
Now supose he comes along and starts to get into his perminant stand at the same time I am at the bottom of my tree putting my stand on. I got there a few minutes before him but he has a PERMINANT stand,,,,,,,so who leaves?
This is one of the problems with perminant stands on public land. In reality he should leave............but how often will the responce be, "hay my stand is alread up over here."? Yes it happens..............
The problem with perminant stands on public land is that invariably the owners of said stands view the area around those stands as THEIR spot. This can lead to problems.
Again, while I always stay away from places I know someone has a perminant stand I also know that I am entitled, so long as I get there first, to set my portable right next to there perminant. And I'm also entitled to ask them to leave when they show up after me.............but I avoid this type thing.
And then there is the issue of guys who will set 4 or 5 or more, and yes they do that here too, stands. So when I go to the woods there are all these spots that "belong" to the guy who set the stands? That will be his perception in many instances. How do you deal with that?
The whole issue of permanant stands on public land is frought with the potential for confrontation unless those involved are willing to compromise and ocassionally be inconviencensed.
Actually it would be, IMHO, a good idea if there was a stated code of ethics about such. Maybe taught at the same time as Hunter Safety..........
