John and all,
Within the last 2 or 3 months, an apparently young Cougar was spotted in a Broken Arrow, Oklahoma, city park. The sightings were taken seriously enough that the park was closed for a few days. Broken Arrow, and the park, are not that far from the Arkansas River--which river could provide a travel route from either Arkansas in the east or from the Colorado and Wyoming areas to the west.
Oh yes, I have read, in a post somewhere, that someone thinks that there is no law against shooting a Cougar in specific states. It would be wise to check Federal laws: I believe, as has been posted elsewhere, that they are a Federally protected animal.
I recently heard a story about a person shooting one and putting it in a freezer at his home. I assume that he intended to have it mounted or some such thing. The Feds, according to this story, knocked on his door,
found the Big Cat, and nailed the shooter's hide to the wall. The Big Cat had a radio transmitter implanted, and it led the Feds directly to his freezer! This might be an apocryphal story, but....
