All you have to do to keep mountain lions out of the area is buy a mountain lion tag.
Had one hanging around here, wife bought a tag and we haven't seen it since.
They killed a couple in town this last summer, guess they were eating house cats.
Custer County SD (Just a cross the state line) has been having a huge ML problem this year. The gave out more tags and also started allowing ML hunting in Custer State Park.
They've been raising heck with elk, deer, and livestock.
