I live in a rural area and I'm completely off the grid, and tax office is telling me I HAVE to register a 911 address, for one 911 does not work at my house, even if it did they do not maintain my rd and no ambulance or fire truck will not and cannot make it down it any way if it rains. So why are they trying to force me to pay for a 911 address ?!!! I already have a po box.. and doesnt 911 go by location of my cell fone anyway? Which by the way cell service is nil yo none also.
