I went to the Dee this weekend, along with around 2000 other paddlers. It was fun, if a bit of a tupperware party, and the carnage as all the beginners swam down town falls in Llangollen was really quite amusing.
Anyway, the most important thing to note now, is that I've found the thermals that God Himself would wear, expect that God could probably make it nice and warm, or conjure up a burning bush or something, so probably wouldn't bother with the thermals anyway.
