I sent this thread to someone and they had more info.
A bear was walking across Rainbow Bridge (Old Hwy 40 at Donner Summit, Truckee) on Sept 15, 2007 when two cars also crossing the bridge scared the bear into jumping over the edge of the bridge. Somehow the bear caught the ledge and was able to pull itself to safety. Authorities decided that nothing could be done to help Saturday night so they returned Sunday morning to find the bear sound asleep on the ledge. ?After securing a net under the bridge the bear was tranquilized, fell into the net, lowered, then woke up and walked out of the net.
