I know legislative initiatives have died in the Montana legislature, but why not a voter initiative? Word it so it only applies to parsels where at least one of the corners is public land of at least 160 acres. Word it so it is the adjacent landowners responsibility to mark what is private, and the sportsmans groups or FWPs responsibility to install a reasonable means of making the crossing without stepping on the private land. It's not just Hunting and fishing, but hiking and all other outdoor activities. Yeah the big ranchers are a rich lobby but the population is what votes, and the ability to access more public land with no rear harm to private land or cost to the taxpayers seems like an easy win at the ballot box.
