I saw the oddest thing yesterday. I was at the courts playing USTA and some 4.0 guys were on a back court playing a flex league doubles match. They were deep in the second set when one of the guys popped the strings on his demo racquet. Apparently, he'd walked out of his house thinking his old sticks were in his car. Just his luck, his partner had busted the strings on his spare racquet the day before so the guy asked the opponents if they had a racquet he could use. They laughed and said, 'Uh, no!'. But there was no quit in this these guys. They still had 1 racquet between them so they improvised, exchanging the racquet after taking their turn at serve and playing 1 against 2. While one guy would play singles, the other stood out of the way (sometimes on the court, others on the sidelines) coaching and cheering his partner on. They put up a valiant fight but got waxed anyway. Still, it was the darndest thing I've seen in a while and they are both warriors in my book. So, in the same situation, what would you have done?
