In 2015, I did the whole thing by the rules. Was one of the first 75 in the fan run line. I wanted rail by the b stage. We got screwed on getting in.. bunch of ppl rushed ahead. I still had a decent spot almost to the rail. Two ppl right in front of me were at the rail, leaned against it and we're visibly exhausted and had no energy the whole show. Over heard them talking about this being 7 or 8th show they had been to in a row, hence thier exhaustion. No matter, they were not giving up an inch of rail space. The one thing that bugs me about U2 shows are ppl who want to be up close but have no enthusiasm. It's frustrating for us who don't get to be tired of going to so many shows. Each concert is a chance to celebrate, jump around, sing my heart out.
Last go around, I hung towards the back of the ga crowd, and had a fantastic time just feeling like I could really let loose and have a good time. As exhilarating as being on the rail is, it can ruin a night to have to feel stressed about it.
