I knew I should have logged into a production box to look at the ACL 
counters.  But no, I thought the former border that I was already logged 
into was good enough.  Apparently not!  :-)  I stopped updating it's 
BOGON list when it was decommissioned and retasked.  I could have sworn 
that was just this past April and the only change since then was 112 and 
113/8 which I accounted for mentally.  Apparently it was longer ago than 
I thought!
