It appears that Rehberg campaign signs were put up on public land, which is not permitted. The signs were posted on state land than a quarter of a mile from Congressman Rehberg’s own house, so it will be hard for him to say he hasn’t seem them, or that he was unaware that the land was public. Rehberg’s been in congress for more than a decade, so he knows better. I guess in his mind he’s above the laws that apply to everyone else.
Montana sign rules state that:
Political signs shall not be placed or allowed in any portion of public right-of-way or on public property.
