I lived in Bozeman, MT when a fellow from my church was attacked by a grizzly in the Taylor's Fork area in the Gallatin River drainage just North of Yellowstone Park. His hunting partner, Dr. Fred B., was also a friend of mine. The gentleman who was attacked was named Mark Matheny. He survived and Fred stitched him up while they were in the Taylor's Fork.
In the years following the attack I heard of other bowhunters who also were charged by grizzlies in this same area. Mark developed UDAP in response to his attack.
