"Neither rain, nor snow, nor sleet, nor hail shall keep the postmen from their appointed rounds."
I guess it is the same for visitors coming to see the Old Faithful geyser at Yellowstone.
The geyser was shrouded by the snow, but people still waited to see it.
When it got closer to showtime, even more people came outdoors.
It was so warm inside that some even ate ice cream while watching the nature show and the silly tourists outside.
