A picture shared this week on social media of a barbed wire fence strung across a popular river in Montana was generating passionate comments. Like it or not, fences over rivers on private property are not illegal.
Regardless of the laws... if you want to drive slow, for the love of God, please stay in the right-hand lane on the interstate. And if you're jamming up traffic on a two-lane PULLOVER. Literally, everyone thanks you.
