When we found we would at least see the captive eagles, and were thus guaranteed success, we headed for Clarksville. On the way we passed a lock and dam on the Mississippi.
I have distinct memories of visiting the locks at Alton when I was a kid. "Ooh, a lock," I said, and Gary immediately took a left toward the river. He knew I'd want to visit it. But, "Why do you like locks so much?" Gary asked.
I said, "They're so cool. They're like steps on the river."
Gary proceeded to explain to me that I was operating under a deep fundamental confusion about locks, that he did not know exactly how locks work but to say they were like steps on the river showed that I had been deceived by whoever had explained locks to me in the past.
Which is why it was so satisfying to see this sign by the lock:
After that victory, the day was a guaranteed success, even though no barges were using the locks at time. We did see about nine Eagles in Clarksville - damnit! Every time I have typed "eagles" in this post, Typepad has capitalized it. I was careful when I told people what I did over the weekend, since "We went to see the Eagles" can have another meaning.
