SoonerCon 2 was held only a few months after SoonerCon 1 so that a "standard" date for the Con could be established. We wanted to have a late fall/early winter con, and it just wouldn't do to go a year until the following fall.
So people dashed around like mad to have a SECOND SoonerCon about four months after the first. This was the main reason for only having two "official" days -- Saturday and Sunday. Also why this con was promoted as "Pure Con Extract" by Con Chair David Means.
I really don't know the source for the lab-rat-in-spacesuit concept for the badges.
Even though the "Friday" schedule -- nothing but video -- begins with "10AM," I am pretty sure that this room started at 10PM, and then ran 24 hours until Sunday afternoon.
