My Lock 33

   On vacation we went on a canal houseboat on the Erie canal. At one point I got out and biked alongside the boat. When I got to lock 33, (a point where a boat can change elevations) the "Lock master" gave me a tour that included the machine that opens the water valves. In the machine, there were electrical relays. Later, when my parents radioed in to get in the lock and pass through, he let me answer them! Then when they got in, they were sealed in, then I got to fill the lock with water. Then I put my bike on top of the boat, said goodbye to the lock master, and floated away.
