I have lived here long enough to...

[SAnd]

The first big thing I remember on moving to Colorado is a BIG rock.
I moved to Greeley in spring 1976. The first excursion I made into the mountains was a drive up to Estes Park. A few months later I drove up again and at the mouth of the Big Thompson was big rock I remembered seeing at Estes Park. Over a hundred people died during the flood that moved that rock 26 (?) miles down the canyon.
When I moved to Denver in 1982 almost a third of the lots in my neighborhood were empty. They are all full now.
Where I worked for 27 years is empty ground now.
Believe or not but the air is cleaner now that then. Some days you couldn't see downtown Denver coming down 25 from the north when you came over the ridge looking into the bowl Denver sits in. Just a layer of brown with a few buildings sticking up through. I spite of the increase in population at least the brown is gone. I don't miss the Brown Cloud.

And about the torpedoes...
