I can say this, of all of the stadiums I have been to, this place has the largest floor. I can not think of any other indoor stadiums with this much room. With all of the term oil in that area, I'm sure it has driven conventions away to. There were only a few things that bugged me. 1 fire marshal made us park all trucks outside. We were allowed to leave trailer and race car inside. All refueling had to be done outside. Actually blocked off part of the street for it. Stadium staff is union, even though we had our own guys, the company had to pay for them to do the work. Other than that the experience was great. Nice place. I will probably make the trip. To bad these guys are not coming back to Indy. I know the race was bad, but you can not discount there effort.
