I never tire of the changing patterns of sky and cloud that our spot between the mountains gives us. Here is a picture from last month and a few lines from the poet Joseph Brodsky that explain as well as any why I am a cloud watcher:

It's you who let
me with your nimbus
trust not in numbers
but in the complete

spurning of weights
and measures in favor
--once and forever--
of phantoms and grace.
