Sad story......
Last Fri I was assigned a tourney game between two very good private schools. Get to the game and the R says, "you have a patchless shirt don't you?" Me - "I carry lots of spare everything." (as is alluded to in this thread, I carry two of almost everything). But, in this case, NO PATCHLESS SHIRT, as I rarely do private schools.
So, during the pre-game, I am metculously cutting off the patch from one of my shirts, with my ole Swiss Army Knife.
Just shows to go you......even the best prepared.......ouch!
