Perfect Duluth Day

Wildcats in Duluth’s Lester Park?

Last weekend, while enjoying a quiet rest on Lester River about one mile up from the main park, I heard what sounded like a cat hissing, but at 20 times the volume of what you’d hear from a house cat. There were five or six of these “roars” followed by a rustling in the under brush at which point I got the hell out of there. I have heard of bobcat sightings in the area but wonder if it might have been something larger, say a mountain lion? Has anyone else had a similar experience or even a sighting?
