We made sure to have had breakfast and be ready to be out and about by 9.30 this morning. Our tunnel passage was booked for 10am, and the Canal and River Trust (CRT) staff are obliged to give you a “safety briefing” half an hour beforehand. Today’s briefing was very Covid-secure, it was shouted across the canal – excellent! The main thing was to check we had a working horn and that we knew to use it if we got stuck. As soon as the only boat coming the other way appeared, we were sent on our way – ten minutes early.
