 Gilchrist says Jim Bridger is a name familiar to many, a man who trapped for years in the West and attended most of the mountain man rendezvous from 1825 to 1840. Jim Bridger is known just for his longevity. The first year he came up, he was the youngest guy on the battalion at 19 years old, but he pretty much went to every single rendezvous. So by the last one, he's the old man. I mean, he's only 35 years old, but he's the old man.
