I'm the same age as the Dragon I did it for about 8 years in the late eighties and early nineties.
I still have all my badges and the bottles of whisky. I've camped in comditions so cold that the tent pegs were frozen into the ground and when it rained the whole site turned into a mud bath. Standing in a foot of mud and water frozen from the knees down and steam and smoke rising from the rest of me at the bonfire was "fun " too.
I loved every minute of my times at the Dragon I only stopped going after a personal tragedy ( nothing to do with the rally it's self).
Yes I think it is still run on the second weekend in Feburary one day I'll go back and do it again.
