Aerosmith Returning to Paso Fair

I thought we were lucky to have Aerosmith come to the Mid State Fair a few years ago but looks like they must like the area because they are returning this year!  Tickets go on sale June 11th for their July 26th fair appearance.  I went to the last concert and it was GREAT.  I read a few days ago that Aerosmith was asking $1 Million for a fair back East. I wonder how much the mid state fair is paying to get them to come back here again?
