Tugboats of Baltimore

The other day I was getting ready to go swimming when I glanced out the window and saw a line of tugboats heading toward me. Naturally, I had a camera close at hand and started snapping. The tugboat parade seems to be an annual event -- the first was held in 2006 -- and it includes tugs, pilot craft, and a variety of other harbor vessels. There were far too many for me to post, but here is some of what I saw.
