This thread is getting so long, that its impossible to go back and check what was said or not said. Frankn, at one point you compared the cost of his land, ($60,000), to the cost of your motor home, what does one have to do with the other? Should he have to pay for your motor home? You didnt buy that motor home to do this project with. Why dont you add the price of your detectors and your home, and get an even bigger number? Also you mentioned that the decendents of the person that hid the treasure might come an claim their share, and then the land owner would get nothing. You keep jumping at straws to get us on your side, (actually I was on your side) You even ask about mineral rights. As far as I know, you just dont go and get mineral rights, you need to prove that there are minerals in the ground, that you are looking for, so you cannot just get the rights, and start digging. If you dont have the $100 to drive and meet the owner, how are you going to buy the mineral rights, as Lastleg suggested?
You also mentioned all the work the owner would have to do to fill all the 100 holes and clear the trash. If you are not digging 100 holes, why would he have to dig 100 holes? Its HIS land, if he digs 100 holes, he can decide to fill or not to fill, leave the trash or not leave the trash. You use the same argument, one version, for the owner, one for yourself.
And contrary to what you believe, I think most of the people following this thread are aware of most of the problems with cache hunting, so please dont talk down to us. It was you that asked for opinions, and now you say we dont know what we are talking about, we dont understand.
Another thing, If I were you, I wouldnt have even started this thread, because while you are trying to convince us that you are right, you keep dropping clues every now and then, and pretty soon, there might be one or two of us that will get interested, then you will have a nice soup.
Your deal with the property expert doesnt sound so good either, 10% finders fee? Wow, you are going to pay him a million dollars? or was it just out of your share, or your partners share? In either case, you are very generous with the expert, but you still feel that the property owner should only get one third. That alone is making enough problems. How are you going to prove the amount of the cache, so you can pay the right %??
Instead of being a thread on how to go about negotiating a good deal for everyone, its turning into a thread about what Not to do. I already know what your reply will be, "go back and read all the post", maybe you should do that also.
