<p>Decided to brave the North Sea on Boxing Day 2011 in aid of the Dolly Foundation (www.thedollyfoundation.co.uk).</p> <p>Fingers crossed for global warming to work it's magic. Tropical sea temperature and a mild sunny morning are what we are hoping for.&nbsp;</p> <p>Bearing in mind we both did this about 10 or so years ago and it was closer to arctic conditions, we fear the worst.....</p>
