You don't get wild horses roaming the countryside in Chicago. It just doesn't happen.
I only saw sights like these clouds when passing through the Smoky Mountains. Here, I can drive for a couple of hours and see it daily, if I choose.
But, of course, there is a down side. This is not a 'side road'. This is the main road in the National Park area (that's a city, not a park...).
Life wouldn't be so interesting if there weren't so many differences between 'here' and 'there'.
