At the risk of introducing a possibly relevant idea into this thread, I thought I read somewhere that the county might sell the land that Willow Springs sits on to provide land for this type (general) of project. That might be just the right amount of land to build a racetrack and a multi-use stadium for both football and baseball. That would leave enough room for parking and/or use of the existing parking across the street at the SBC would allow for more development on the Willow Springs site. Also, as long as new barns were constructed on the original land donated, would that still cover the county under the terms of the original donation? Just as an idea to cir vent this type of issue, since some of the barns will be rebuilt, couldn't (asking here) they be rebuilt on less prime land (far corner in a less desirable area) and free up the space next to the SBC?
Of course, Willow Springs flooded during the big flood a few years ago to the point where I recall debris in the trees about 10-15 feet above the ground. Also, I'd agree that the racetrack comes first and then some pitch is made for the stadium and only if a team is secured for it. A multi-use stadium is the way to go so it could accommodate both teams if secured, either/or if only one team is secured, and to minimize risk if no team is secured.
That also being said, I personally think (no links at this time but thanks for not asking) that SA can not support three major league sports. The Spurs have a hard enough time squeezing money out of the people and corporations of the city. They constantly work all angles and search endlessly for new revenue streams to make it all work. This is a championship team and it still requires this type of effort. Most teams that relocate are not elite level teams and unless the Texans or Cowboys decide to move to SA, there would be some initial interest but unless the team started winning quickly, interest would diminish rapidly. Given the limited income of the residents of SA, choices have to be made. Do you watch your beloved world championship San Antonio Spurs whom you've had a love/hate relationship with for most of your life, or do you watch the relocated franchise that is struggling to stay out of the cellar in their rankings. As a corporate sponser with limited budgets for such things, do you associate with a clear winner or a possible perennial loser?
