If you were in Australia, Blackcatter, you could most definitely surf on Christmas Day - a lot of us do. It's midsummer here then.
Typical Christmas Day at chez JennyO is a barbeque with friends under the big shady tree - steaks or whatever you fancy sizzling, prawns, salad, plenty of coldies, a w(h)ine or two, and a session. Tempted??
