Thanks for the response and various links. It seems like if I tell of any hazards -such as unlevel ground or toppled trees that haven't quite toppled all the way (which seem to be numerous around town due to wind storms last year) and maybe post a note to geocache at your own risk, that might help to keep geocachers safe and go a long way toward protecting against liabilty. I want to make the search a safe and happy experience for both the geocacher and the person kind enough to let me locate a cache on the property.
