yeah actually do. have plaques, 300 rings, as well as everyone can look up a persons "300" games in national bowling hall of fame, or through USBC on bowl.com. My favorite 300 was when I did it in the Utah state tournament. I go to Albuquerque to bowl nationals in 3 weeks, now that would be awesome to get one there. One other thing to note is I have 13 300's, but 7 were during "sanctioned" leagues or tournaments, the rest were just bowling with friends family or alone practicing, so only 7 of them would be able to be looked up for proof.
