Boring?
Ultimate frisbee (cross between football and hockey) and frisbee lacrosse are two of the greatest amatuer/unorganized sports. Go to any college campus on a nice May day and you'll always see ultimate frisbee. Also try playing catch with a frisbee where you have to "catch" it with a hunting knife. Not good for the frisbee, but its a lot of fun.
“Also try playing catch with a frisbee where you have to “catch” it with a hunting knife.”
So, I am going to run around with a 6” blade and try to catch a frisbee. What could possibly go wrong?
