I'm located in Marion County, SW of Des Moines. I saw a lion here 4 years ago, 4 miles west of Knoxville. Local DNR officer checked the tracks and could not confirm the sighting (said the tracks in the dust beside the road were too "smudged"
BTW, that lion was within 20 yards of a favorite camp site of mine.
I am ALWAYS armed when I'm in rural areas nowdays!
Found this pic of the Meringo Lion online
