It's easy to see why anyone would love Yosemite National Park: Half Dome, giant sequoias, gushing waterfalls (well, in the right season).
One man who knows Yosemite better than most is Fred Koegler. This summer, he's celebrating his 50th season as a park ranger there.
Koegler's history with the park goes back to the summer of 1965, when needed a summer job in college. He later became a school teacher and coach at Verdugo High School. But, he kept ranger role at Yosemite on the side. It eventually progressed to the position he holds today: Horse ranger.
"It's just great to be in the outdoors and patrol the campground, and talk to many, many people from all over the world and the United States, and some kids that have never seen a horse in their life," he said. "To see their smile after they pet my horse, King, and it's just a thrill to be here every summer."
