I still see a lot of crystal clear skies with dark blue. In fact, today is one of them, though we are starting to see some high clouds as result of a storm system approaching for tomorrow.
On a few summer days last year, I sat on my deck and watched thunderheads form. Still a spectacular sight. Though not quite a spectacular as from a Deep South area like Alabama or Texas.
I actually remember more haze in my younger days. Back in the 1970s, air pollution was a much bigger problem, especially in NJ.
