I might have to resort to posting text excerpts into google blog search and seeing if it can figure it out.
ETA: I found it. It took typing in 5 different key sentences to google's blog search before it turned up. Good grief, when I want to hide, I do know how to go about it. It was lucky that most of the posts for that blog were written on my Palm first so I could look them up, or I'd never have found it.
