Wikipedia isn't much more than a glorified blog. Also, the entry regarding the Nationals currently having a team in Pulaski is completely false. It is indeed a 9-team league this year.
Lee Landers, the league president, is/has been in talks (at least as of last February) with the Mexican league and the Mariners for a team in 2008. However, the Pulaksi government was insisting that whoever moves reimburse the city for something like $5 million for recent renovations (about 5 or 6 times more than Calfee Stadium is worth) and then pay rent. That's quite a hefty load for a rookie league team, and the Mariners essentially had told the Appy League that if they did provide a team, it would not be in Pulaski. Until Pulaski comes to its senses, I doubt anybody is going to play there.
