i dont have a facility...

but then, i think if you cannot trust your close friends and your family with your valuable stuff, you are pretty much screwed. if the situation requires it, i would trust them to the point of giving them the keys to my home. lets say im in an accident and end up temporarily stuck in a hospital, those that i consider close can be trusted to the point of giving them my keys to get something from my home for me. without any worries that they might screw it up.

so, for me, when it comes to friends and family, its a clear-cut case. its a common sense thing, you should know your close friends and family good enough to know who can be trusted.

i think the real problem is that break-ins, theft, and acts of sabotage do happen. so keeping knowledge of the location of a facility limited to a small amount of people can really make sense. it doesnt matter much for small collections that are within someones home, where someone is around pretty much all the time. such small collections are basically similar to having a valuable comic collection or a valuable gun collection, or having a small workshop with valuable tools attached to your house. it also doesnt matter for really big facilities that have security cameras and reinforced doors. those inbetween, with a small facility and limited budget for security, but nonetheless some really valuable snakes, have the highest risks.

so i think how to deal with people you do not know well is more interesting. and it depends a lot on circumstances, like the value, size, and location of the collection/facility, if there is significant cashflow or not, and how much has been invested in security.
