I'm 5 feet tall and have had the same problem of not being able to see. I ponied up and paid for 5th row tickets once and it was so worth it. We noticed people like you who would just casually make your way up to our section and we definitely reported you to security. Why didn't you just pay to get better seats?

When I was younger I would go to concerts and sat really far away. Ever since I sat 5th row, I don't think I'll ever want to go back. It's such a different experience, it's unreal. It can get expensive, but luckily there are only a few artists that I like enough to pay that much money.
