I read the start of the long instructions. Top lock should be filled – yes it already was full, so I opened the gate and Shane went in. The middle lock should be only part way, I thought so and the bottom looked empty but seemed very far away. We had seen someone else a few days ago at the bottom lock saying he couldn’t see the coloured panels as he went through so I didn’t go and look for them. That was a mistake, but I wouldn’t have seen them either, but I could have checked more thoroughly.
