Laramie, WY – The author of a book on mountain lions says Wyoming communities need to be aware that they can cause the same problems that they did in Colorado. David Baron wrote the book "The Beast in the Garden" about a series of mountain lion attacks in Boulder, Colorado. Baron says besides pets, the mountain lions also attacked and killed people on the edge of town. He warns that those who live near mountain areas need to be extra careful. Baron says people who attack deer to their property for asthetic reasons also attract lions. He says the mountain lions simply will follow the deer to the property. Baron speaks Thursday night at 7:30 in the U-W Classroom Building.
