Follow-up (sort of)

First of all, Ohio voters approved Issue 3 yesterday. The Home team won by a touchdown -- the final score was Critical Thinkers 53, Visitors 47.

Also, this morning I happened across this phenomenal PowerPoint presentation. Put together by Kevin Estela of Wilderness Learning Center, it's one of the best primers I've seen on the subject.
