It wasn’t long before we reached the flood lock. There were enormous signs saying not to proceed “past this point” if the red light was flashing. We couldn’t see a light, and we couldn’t see a mooring either – are you supposed to wind in those circumstances? The rain came on as we approached the lock. We had seen on our walk the previous night that there were contradictory instructions. A large sign indicated that the lock was normally fixed open between April and September. It had been open two years ago, but this year it was not. One paddle at each end was marked in red and signs said to leave these open. One of them was broken though, so it was impossible to follow that instruction.
