Wheelhouse and final lock!

We were allowed into the wheelhouse to get a feel for the navigational methods and challenges of the captian and first mate.  They use radar, naturally,  and a sort of system where they're able to identify other boats in the area--their size, what they're carrying, etc. No auto-pilot whatsoever.        We also went through our final of 67 locks--and this one was a biggy, as you can see from the photos.

       Because it was sunny, we were able to enjoy the upper deck.
