I'm posting again to fine tune my first answer. There are several folks on this forum who I have tried to help (and will again) find some good places to hunt. Potentially RICH places to hunt and received their thanks. Those were great responses. There were 2 forum members I attempted to help last summer and did not get any appreciation from them after emailing sat photos, modern maps, and CW era maps of a battlesite. I gave them easy directions on driving to this location as a side trip to a formal hunt in northern Louisiana. Did I want anything from them? Yep. A simple "Thank you, man, appreciate the help", would have been all that was wanted. But, that did not happen. It would have been nice to hear from them if they'd found anything. I did not want or expect any items from that site........just the knowledge that my attempts to help was fruitful. I heard nothing. Those 2 gentlemen won't get any info from me again.
Fast forward to just a few months ago. Another forum member, living in Louisiana, received some specific info from me that may not have been easily found by anyone else. That individual told me "Thank you" for the info and help. Was I looking for some "smooghing"? Hell, no. Just basic common courtesy. Afterward, I loaded him down with hard to get materials. Why? Because he earned it through his courtesy plus the fact that I could never check and search for everything in that information. Truly, I ain't' never gonna get it ALL.

Plus, this person told me that he'd let me know what he and his hunting partner find.

That is ALL that I was asking. Knowing if your research bears fruit is a "valuable" commodity.
I enjoy helping good people. How do I know if someone is a "good" person? Gut feelings. Pure and simple.
There are several coinshooting sites within walking distance of my home that are on private property; ooooolld property, that I have permission to hunt, anytime I want. Will I share those sites with the local coinshooters? NO. I will take my son, but no one else. Why? The "leader of the pack" attempted to embarrass me in public one day for no reason whatsoever. His action was purely childish in nature and I decided that day that I'd NEVER try to help him and his "crew". Am I being childish? NO. I figure that if that guy is so petty on a meaningless situation, he is not trustworthy on the important things. NUFF SAID.
