I know what you mean. After 35 or so years of attending the State Fair of Texas, I know how to navigate it and avoid situations that I don't like.
And I'm okay managing UT home games amongst 100,000 people just fine, for the same reasons.
But I attended one day of the ACL Music Festival a couple of years ago, and it was just absolutely miserable. My days of attending music festivals are officially over, I suppose. And I'm fine with that.
