Bottom line is either you are welcome or you are not.. You
have no say in the matter.
If I catch anyone on my property, without my permission, I will
do my best to prosecute!
A simple conversation to ask permission ain't that difficult.

One more thing. Be careful who you take to your permissions. Many
will become your detecting buddy just to gain location of and/or
access to your spots.
If caught they will say you granted them permission... Chances are
you will both be banned.
