The fair was this weekend. I was in the vicinity of Har Mar, but only briefly, and I did not have time to stop in this weekend. But The Lorax did, and he has blogged about it here.
Here are a couple of my earlier posts on this event, including last years:
Twin Cities Home Schooling Creationist Science Fair Photos
Some Sick Atheist Demeans Kids ... Photographic Evidence Destroyed
