the avon is also a bitch to get out of unless you can climb concrete / metal banks though. I looked for a guy who had been knocked off a bridge by a car (North parade) in 2000. Was found nearly a week later, 30 yards from where he went in, trapped in bushes by a bank.
A friend of mine died a number of years ago whilst jet skiing on a hot summers day. He jumped off the jet ski and had a heart attack / shock from the cold water. He was actually and incredibly talanted, young professional windsurfer so it’s not even a ‘get used to it’ tyoe thing. It can just strike. Very sad and I can’t help but feel for others in the same situation
