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.<p>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.
