57-year-old Jim Litz was riding his bicycle to work in Missoula, Montana when he came over a rise and saw a 300-pound black bear right in front of him! He didn't even have time to brake, and ran right into the bear. The two tumbled over together before the bear ran away. The weight of the bear had cracked Litz' helmet, and he had claw scratches over his torso.
Litz's wife drove by soon after and took her husband to Community Medical Center, and he immediately called Montana Fish, Wildlife and Parks to report the unusual collision. Game wardens told him they didn't think the animal was seriously injured, but was more likely suffering from some bruised ribs - just like Litz.
