William Lum, who won the 100 mph class with his daughter in May, was a course worker in September, stationed in the Narrows. He was accompanied by his wife and another daughter, and, since he's a geologist, he was in the right place. Thanks, Bill! In this video clip, you can perhaps hear that I beeped my horn three times (once for each of them) as I approached their location.
Also, note the coyote crossing the road in front of the car right after the finish line.
