When I was heavily into cars, in my youth, one thing I learned was that friendships and alliances often meant nothing when it came to things people
really want badly....... So, If for instance, I found an old AC / Shelby Cobra in a barn for $500, I'd tell none of my "gearhead" buddies until after I had bought it. After one or two lost deals,
I figured it was best to keep it quiet. However, there were one or two close freinds who were trustworthy enough to not just tell, but who would actually help me haul, trailer, retrieve, whatever. Those few individuals are still my friends decades later. The others? long gone,
Let's just say I discriminated out the foil and pulltabs, in a sense.
I'd think it'd be best to be upfront about the "hunting later" thing in the beginning, some sort of courtesy agreement? Not everyone would have the same unspoken rules in mind.
If someone offered to take to their "secret spot" but only requested I not return without them along, I would think it was a great offer, and would not be offended at all. I have narrowed my friends down to a handfull of really great people over the years, and I wouldn't trade their friendship for all the coins, relics, and jewelry in the world, even though I covet treasure as much as anyone.
And no, I never did find a cobra in a barn, but if anyone ever finds one, lemme know.
I'll be glad to appraise it for ya............
