Mice, apparently.  You see, it's 6:59AM and I'm sitting outside of our garage watching strangers peruse through our belongings (a fine Arkansas tradition).  As an added bonus, about fifteen minutes I noticed a small brown blur darting among some of our stored items.  Yep, a field mouse.  I hope (HOPE) he found his way inside the garage this morning as I was setting out stuff.  The alternative is too unpleasant to contemplate at such an early hour.
