I have decided to do some research on a old ballpark locally. What I want to ask it.. Does anyone know where to look or how to find out what demolition company was used to tear down a ballpark. I'm talking back in the 60's. Does a company have to file for a permit..etc with the city to take down something this big? If so, what department would I contact locally (it was a local ballpark) to see if I can find the company that did the demolition? Any help would be appreciated as this is all new to me and I do not have a clue on where to start.

Thanks for the read..

David.
