This is me to a tee. lol. I haven't been to one of the opening night concerts since the Beach Boys. I was there for, at most, 20 minutes. My wife, kids, and I left for all the reasons you stated above.
He77, the people wouldn't even move their hands, propping themselves up, to let us out. Finally, I told the kids, "just walk, where ever you have to, to get out."
