Forgot to mention, last week I had a visit from Graham and Pauline to say that Deeptrek will be returning to Llyn Cerrig Bach in March, bringing with them more sophisticated diving equipment.
I shall be looking forward to meeting them again at the lake and spending time observing once more.
Managed to buy an Interim Report 1945 edition on Llyn Cerrig Bach, signed by Sir Cyril Fox for £9 on e-bay!
