If you are in Holland between 18-20 august and fancy some frisbee playing, join the A*DAM hat tournament. You sign up individually and teams will be formed on the day itself by drawing names out of a hat... hence the name. ;)
Sign-up fee is €60 p.p. and for that you get a lot: includes cruise, amsterdam, camping, breakfast, teamshirt, teammates, grass to play on, canteen, other teams to play against, dinner, party, DJ, dancing, sleeping, toilets, Relaxfast, Relax-DJ, sunshine (not guaranteed), price-ceremony, smiles and kisses! The tournament will be played at sportpark Wartburgia, close to the Amstel train station, 5 min. from Central Station.
