Good morning to the list, I am waiting for my unit to be ordered. I was asking a dealer a question that I think would be quite important for safety reasons. I have a 50 ft. by 50 ft. area that I want to block out so that no matter where I'm walking this area which is not fenced in will not be part of my travel path. There are more areas such as flower beds that do have rock borders, but the vegetable garden does not so how can I label these as a keep out area? Thank you.
