Moon earned his seat in the 2009 World Series of Poker no-limit Texas hold'em Main Event by winning a $130 satellite tournament at the Wheeling Island Casino in Wheeling, West Virginia. He lost in two Wheeling Island tournaments before finishing in first place on his third attempt, winning a $10,000 main event seat and $6,000 for expenses. The event marked Moon's first time playing in the WSOP, as well as visiting Las Vegas, Nevada and riding in a commercial plane. Due to the econommic downturn's impact on the logging business, Moon considered keeping the $10,000 instead of entering the tournament, but decided to play after visiting the Rio All Suite Hotel and Casino and watching World Series games there.
