Yes that was at one of Grady's tournaments. It was held at the Spot Shot in Portland Main, which at the time was owned by the late Kerry Hebert. Grady was living in ME at the time. It was a $20,000 added event and it was Nov 1-5, 2000 -- I know because I have the poster for it on my wall, lol.
Incidentally, that tournament was about the last major tournament for three notable players: 'Boston Shorty', Johnny Ervolino and Larry Lisciotti -- all of whom played in it. Along with a much younger player that also left us way too soon -- George 'Ginky' San Souci
