Called the Herder of Cats, who is a Most Excellent Butch and lives nearby. Fortunately she was free, and showed me the trick - use your legs to POOOOSH. *Sproing* TADAAAAH.

All of the presents (except for the one King Arthur Flour forgot to include, whoops, that means a quickie trip to Surly Table on the way out of town) are located, as is the box supply. I am, however, zapped and am checking in undercover RIGHT NOW.
