If the A's stadium is located near the Warm Springs station it will be much better than if it were in the wasteland 2 miles away. (I would prefer it be in downtown Oakland on the current Auto Row) I have never been to an A's game without taking BART and I can't imagine getting to the game any other way. The freeway is always jacked. But I think they might have been waiting for funding, and it seems to soon be assured.
On the other side of the country, the Tampa Rays are looking to locate near a rail station. This is in a place that hasn't even started the most serious movements toward rail lines. But its nice to see the team looking ahead.
