Having never been to spring training, this discussion has made realize why the Brewers are still in Maryvale. The facility is mostly fine, slightly lacking in space and slightly outdated but otherwise fine. It even has some advantages compared to other facilities. The neighborhood is unappealing to the eyes and there is nothing to do nearby...but otherwise there is no evidence that it is detrimentally affecting anyone. Spring training isn't that profitable. The Brewers are definitely NOT going to get their investment back on a new facility, so there's no rush to move. Of course they will move if taxpayers are going to throw $70 million at the Brewers. If that doesn't happen, the Brewers will eventually spend their $20 million upgrading Maryvale and life will go on. Side note: Maryvale itself is a great example of the 'intangible' economic impact--suggesting that in some cases it may literally be zero. In the land of sprawl and highways, nobody has to spend money in any particular town and a spring training facility isn't enough of a jolt to spark activity.
