Yup, Dodger Stadium will be #3, sad to say. It's certainly considered one of the best, if not the best, ballpark in MLB. The remaining 'relic' from the Dodgers' & Giants' late 50's move to the West Coast, sounding the death knell of the Pacific Coast League, which many thought was almost the equal of MLB.
What's amazing is that Dodger Stadium will be the third oldest ballpark in MLB after Ruth's House is gone. Still the nicest park in the nation, imo.
Safeco (up here in Seattle) is quality ballpark, but there's a big problem -- fans are packed in like sardines. The seats are only about a foot and half wide and very uncomfortable. Last game I attended some wide-bodied woman sitting next to me kept spilling my beer with her rolls of fat.
Dodger Stadium seats, otoh, are wide and padded. ....a pleasure. And a fan can listen to the best in the business call the game: Vin Scully.
