Kayaking Penobscot River (Hampden to Bangor)

I kayaked 6.5 miles today on the Penobscot River from Hamlin's Marina in Hampden to the railroad bridge downstream from EMMC.   

It was a beautiful day and I timed my trip so that I'd turn around when the tide changed.  While this is a fun place to kayak, the amount of abandoned industrial and marine equipment lining the shore (and underwater) is disheartening.
