I'll add that I just got district 1 at 136.5, too.
[edit] I should note that my scanner (436HP) specifically shows PLs as "PLXXX.X". Manual states that "CXXX.X" can be CTCSS, DCS, and something else (can't remember). If the 136.5 is indeed a CTCSS tone, I wonder why there are two ways of showing that. Perhaps the "PL" is reserved for amateur frequencies? Meh, I digress.... a question for the uniden tech forums I suppose.
