I think USA Today has forgotten how dangerous most industry is. Especially construction work. 8,000 workers in an environment that hazardous are going to injure themselves. At a concert with 8,000 people you can expect that there will be medical emergencies, fights, and 911 calls galore. That's without heavy lifting, and machinery that can remove limbs.
What's surprising to me is that they haven't had a fatal accident yet. After a couple years of operation you would expect at least 1-2 people to die actuarially speaking in a worker population that large.
