Thats a tough one.
I've been in the exact spot and I can tell you that there are no easy answers.
I always (wrongly I guess), assumed that others would keep your areas to themselves and wouldnt try to horn in on another guys spot. At the very least I expected a phone call asking if it was alright for them the apply or hunt in the areas I'd showed them.
I was wrong about that and I've been burned several times on it.
I also always (wrongly I guess), assumed that when I went on a hunt with someone that they'd do 50% of the research, scouting, etc.
I grew tired of doing a majority of the research, a majority of the scouting, providing a majority of the gear, and then have friends show up to do the shooting and head home.
It has strained or cost me some friendships, no doubt. I hate that it has, but, I just couldnt continue to have others view my time and resources as expendable and their time and resources too valuable to help in a collabrative hunting effort.
I'll take part of the blame as I should have never let things get that out-of-whack in regard to time spent by each in regard to hunts. I should have demanded that they do their share. I didnt do that, I let it slide and slide until it was just flat stupid. I finally figured that if all my friends are going to do is show up for the hunt, after I'd done all the work, I'd be much better off just hunting solo.
What I've learned from some of my mistakes, and those of others, is that if I now take someone to a spot, I just assume they'll be back to hunt the chit out of it. I dont expect a phone call to ask either.
If I have a spot that I dont want others to know about...I keep it to myself.
When I apply for hunts in Wyoming or any other state, I apply solo and expect to hunt solo every time. I dont rely on others for help, dont expect anything of anyone any longer.
That said, I enjoy helping others and I like to see others be successful. I also enjoy having people help me out on some of my hunts, and of course, really enjoy hunting with my immediate family. I also enjoy having other people in camp, helping to pack game, glass, etc.
I also strongly believe that when it comes to finding and hunting quality animals, its best to fly solo. The main reason is because I dont want anyone to interfere with how, when, why, or even if I even want to hunt. I want MY hunt to go MY way. I also have nobody to blame if my hunt doesnt pan out. I'm not waiting on anyone, they arent waiting on me. If I dont feel like hunting at first light, I dont have to. If I feel like walking 2 hours in the dark, nobody will bit ch about it.
No matter what though, you're going to be an a-hole...I can tell you that. Its always the other guys fault.
