The lock keeper was apologetic that we were losing our place in the queue – I said that I realised we were giving way to the King’s Swan Uppers, and we knew our place (I’m not a royalist, but in a lock, the lock keeper’s word is law). We were on our way soon enough, though it was surprisingly late in the morning by now. We stopped for lunch when we spotted a suitable bit of bank, but then pressed on. We passed the group of boats again moored appropriately enough outside The Swan in Staines.
