We own about 3 acres surrounding us . It is dangerous with deep holes , old glass and metal trash someone dumped years ago . AND there is now a beaver pond creating deep dirty water . We don't want anyone to get hurt AND we don't want to be liable if they do get hurt . What specific sign will be legal ? Keep Out , Danger , no trespassing , posted , etc . AND is there a specific legal distance between signs and at what height ? Thank you for any assistance you may be able to offer .I made a mistake. Atty Futeral was the BEST ANSWER! not Atty Taylor. Couldn't figure out how to fix my mistake.
