Wireless at the ballpark

Last week we were able to take a side trip to SBC park in San Francisco to catch a ballgame.  SBC is now my favoriate park.  That was the second out of town park I've been able to visit this year and both had fee WiFi at the park.  This led me to ask, why don't we have WiFi at Safeco Field?  How does a team owned by guys who made their fortunes on wireless phones and PC software not have WiFi in their home ballpark?

By the way, did you know that Bill Neukom is one of the Giant's general partners?
