Rainiers games are great. For less than $15 (less than $10 for many seats) you can get right up close to the field to watch these guys that are one step away from the Mariners. (The Rainiers are the Mariners' AAA farm team, so these are the best in the organization who are not actually playing w/ the M's.) Watch for occasional M's players coming back from injuries, etc., too. I should mention that there is a lot of good food for reasonable prices. Thursday evening games are dollar deals ($1 beer, $1 hot dogs, $1 ice cream, etc.), and every Friday night game has fireworks. Definitely a great family outing.
