The 2 wire fence has about 1500ft of wire so it's really overpowered, but I wanted to be sure that any grass or weeds touching it would not drain the system too much to be effective.
It's only been on 5 days and no dead critters found yet, but I was worried that a bear would plow thru it so I put flagging tape on it in 3 areas where it crosses a walking path to make it more visible.
