Do yourself a favor and DO NOT use that form! First of all it says DIG and repair as best I can? That is going to throw up a bad flag. Second of all it says something about injuries resulting from the owners negligents?? If you hand me a letter and it talks about my negligents and you wanting permission I would run you off! You would be better off having some business cards printed up with your contact info on one side and a very simple liability waiver on the back. My card simply says: OWNER OF THIS PROPERTY NOT RESPONSIBLE FOR INJURY WHILE ON HIS/HER PROPERTY. Only bring up the liability if the issue is a deal breaker. I think I have had to use it one time and owner of the property I wanted to hunt was a lawyer.
