This is pretty neat when I heard about it. If you bring a

DS or DSi to a Seattle Mariners home game at Safeco Field, you can download the

Fan Network application and view interactive baseball content on your DS while watching the Mariners game!

If you don't have a

DS, then you can rent a Mariners DSi at the game for free if there are any available.

Fan Network? You can use the

DS or DSi to order food at the game, track game stats and pitches for each player, see live video and ESPN radio broadcasts.
I'm honestly not that big a fan of baseball, but it would be cool to go to a Mariners game just to check that out. I've never actually been to see a MLB baseball game in person. It would be of more interest to me if there was a

Fan Network at the Rose Garden for the Portland Trailblazers, which is our local sports team.
If you're a Mariners fan, baseball fan, or live in Seattle, check it out. That's pretty rad to be hooked up with

and ESPN if you go to Mariner games.
