According to my YELP! weekend updates, there will be a "Cardboard Tube Fighting League Tournament- Washington War Dance" tomorrow, Saturday, July 26th, at 3pm on the Mall. This free event no doubt will bring out some interesting people, so be sure to bring along your camera!!!
Attire? "Cardboard armor, costumes encouraged. Business suits are also highly encouraged for this event"
"Let's beat each other up with cardboard tubes!"
While I unfortunately have a conflict and will be unable to make the event, figured I would pass it along... Only in Washington...
