You may have heard of some old laws in Montana, that are still "on the books." Silly laws like, "You can't eat ice cream on a Sunday," or "Single women are not allowed to fish alone." But, thanks to an old Montana law, some students in Conrad, MT had a great senior prank for their principal.

According to Sheriff Carl Suta's Facebook page

It's still on the Montana Law that if a student rides a horse to school the principal has to feed, water, and walk your horse. Six of our seniors are aware of this law on their last day of school ever. I think we might be rednecks!
