Had a tough sniffing job last Friday.  2 floors of a 3-decker in Worcester.
Students living there.  Some areas had so much stuff, it was hard to know where to start sniffing.  I had to lead my handler because there was no room for both of us.  Love to lead, although she does not like it.  No time to ponder when I am on the job, I tell her.  Yep!
