Build it and they will come! I believe that was the theme of a fantasy movie entitled "A Field of Dreams."
Will the businesses and people come after the parking garage is completed? Do we have any examples where such a place has worked? Surely, someone can come up with a project like this that was successful. If such an example exists, it would be very, very helpful if that success is documented to prove to the public that it can work.
I can point out at least one example of a several million dollar parking garage that was constructed in Evansville, Ind. to help re-invigorate the downtown area. In their case, the garage was built and, I'm sad to say, they didn't come!
