I posted the link under a particular question, but thought I'd repeat it in a more general-interest way.
I ran across this great collection of photos from Davis-Monthan storage facility in the (mostly) 1966-68 period, posted by a gentleman named Neil Aird. Lots of gorgeous color shots of familiar and less-so aircraft to drool over.

The Davis-Monthan section is but part of a larger collection, assembled, as the author says, from a lifetime of plane-spotting. It's well worth spending some time exploring, something there for nearly every aviation era fan.
