Going up the masts (not necessary when sailing, but sometimes necessary to fix things).
Going through locks on the rivers. I've lost count of how many I've been through so far, probably about 15. At the lock below Louisville, on the Ohio River, I actually steered us into the lock and up to the lock wall myself. OK, well, the Captain was standing right next to me the whole time, talking me through it. But still, I was pretty pleased with myself.
Seeing the Saint Louis Arch from the river. I had no idea that I'd be seeing the arch again so soon, and in such singular circumstances.
Misty mornings on the rivers.
And, of course, cannons. (I'm sure that nautical enthusiasts in the audience will be happy to inform us that on a ship they're actually called "guns," not "cannons." But seriously... cannons!)
Boom. We're in Huntington, West Virginia at the moment, and will be here through the 13th. After that, we'll be in Marietta, Ohio from the 16th through the 20th.
