If you've the good fortune of being in Amsterdam this weekend, come down to the frisbee fields near Olympic Stadium and watch the fun at one of Europe's largest and most insane ultimate frisbee competitions: Windmill Windup.

I'm handling video so expect some highlights this weekend. Today I watched the Danish national team take on our own Amsterdam Red Lights. Also saw Paris's Ultimate Vibration beating an Italian team. While the Finnish ladies national team seemed to have an easy time with the Czech women. Fun times in the rainy weather.

Admission is free. Games are going all day and into the night. Parties happen in between. Food available for cheap. More info on the site.
