Sounds like you missed out on shed loads of fun dryhen... we cycled into town from Houx Annex, several pints and and some grub mid afternoon, made a bit of a 'day' of it, took a gander at the cars at the starting point, then wondered through the parade route to find a bar.. .
We found one with tables outside next to the road and set up camp for the rest of the day. The crowd grew and we were joined by other Brits and Danes all getting completely sh*t faced, by the time the parade started the atmosphere was fantastic!
After the parade, we stayed to shout at passing cars who stopped at the traffic lights to spin their wheels... some very impressive performances even from some of the locals!!
Got a bit lost on the way back but followed the fireworks to camp.
I think the rule here is that the more beer, the more fun you have.
