(YELLOWSTONE, N.P.) — A Massachusetts man nearly died Saturday during a bison attack in Yellowstone. Investigators say the victim, who is in his mid-50s, let the bull get within a few feet of him at the Norris campground before the animal attacked. The man was tossed nearly 10 feet in the air and broke several bones during the incident. He was later airlifted to EIRMC and is expected to recover. Park rules forbid visitors from being within 25 yards of large animals, and within 100 yards of bears.
