[Rockhounds] seeking information

[Dennis Buffenmyer]

Kind list members,
I am seeking assistance in locating the specifics for a law I "THINK" I 
had read about, but, considering the effort I have put into it, it may 
have simply been a wishful manifestation. I believe the law to be of 
either Michigan or Wisconsin legislation, whereby, if a person, 
individually, or as part of group, obtains permission to access property 
( in this case to collect rocks ) they relinquish any right to sue or 
hold liable the property owner, in exchange for the privilege of their 
activity. However, if you are trespassing, the individual or group can 
be held liable to the highest account, of any infraction incurred to the 
property owner.
Any assistance in identifying such legislation would be greatly 
appreciated!!!!

Thanks!
Happy Rockin'!
