Yellowstone is home to two thirds of the world's geysers, and Old Faithful is known to be the most consistent, blowing every half hour to two hours for a minute or so at a time. The park rangers are able to predict each eruption to within ten minutes, and a thousand or so people turn out on busy days to watch them.
It's easy to think of Yellowstone as a place infested with tourists, choking away the wildlife and ruining any hope for an escape from modern life. This is the lazy man's attitude. The trick to enjoying a place as heavily visited as Yellowstone is to leave the damn car. I know that sounds obvious, but it's amazing how few people take advantage of it.
The place was so still I could easily hear the conversation of two fisherman all the way across the lake. They sounded kind of like sports commentators.
"Great day for fishing, right Dave?"
"You said it, Bob."
"Wind's really died down, huh?"
"That's right Bob."
