Where is the sanity is going into the ice cold ocean in December especially if there have been weather warnings issued?
Beyond me personally as to why anyone would want to do it.
I do not like hardship of any description and my response to, say, going camping (traditional style) would be along the lines of "I had to spend 6 years back along roughing it living in bedsits - not by choice! So I'm not going to do any roughing it ever again thank you".
An invite to freeze my arse off would be "You think you're getting me into a cold polluted British sea in the summer even = NO chance" - still less doing that in the winter.....
