When fire bombing and spraying in Ontario we always used roads, }{ hardly likely that the Government would pave such places} some of them were "interesting" with only about four feet clearance on the wing tips, but one gets pretty good at judging it after a few seasons, but AG Cats are built pretty tough even if one does clip the odd wing tip, the only big risk are hunters on four wheelers who don't seem able to read the large placards informing them of what's going on, but that a whole different story!
