I enjoyed the sheepdog demonstration, border collies herding sheep and then ducks. head58 and aliwings brought their son and he appeared to enjoy himself at teh festival as well.
The main reason I'm posting about it now though, is that I just remembered what happened when I ordered food for emilytheslayer and I. I'd gotten a pulled pork sandwich ($5), a hamburger ($4), a hot dog($3) and a bottle of diet coke ($2). The guy behind the counter told me the total was $5 factorial. I was greatly pleased.
