After lunch at the pub in Sprotbrough we went a slightly long way back to the boat via the lock. A large wide boat was rising in it as we walked by. Just before the lock went out of sight, I saw that the gates were partially open, but not moving. I didn’t expect to have any valuable insight to offer so we carried on to Bartimaeus. I had been wondering about moving on, but knowing the lock wasn’t working made that decision pretty simple. Later that afternoon two boats came through, so I knew things were resolved, but moving on could wait until the morning.
