I just read a thing in the USMS magazine about submerging during backstroke - and I was focusing on that today too. I think your view was better!
I can't comprehend how one can concentrate on the peace described while swimming in 50F water - I would be fighting to survive. Maybe the temperature is part of the beauty? Maybe someday I'll have the courage to experience for myself.
Yes! guess warmer would be a little better, but no ice sounds great.
WOW! Sounds perfect!
