1. The ban is really a way to crack down on those who smoke in their seats. Having an area to smoke in is tacit approval to smoke in their facility, so those who are rule benders are only slightly bending the old rule. By banning smoking, you are putting more teeth into the policy and making it easier on security.
2. The tailgate hour limits is a bigger deal and will push STHs to the private lots surrounding the stadium.
I wish I would have made Judman's point and also pointed out that those who abide by the new tailgate rule means all those cars will be pushed into higher congested times, making it worse.
I know there are hand stamps for this, but that is a security nightmare when people are drinking. No where else can you leave a stadium and come back in. I could have made a better point on the security issue.
