I will say I'm the parent of a SS4 athlete and being in the arena was a fun experience. Did I find it necessary? No. Now I'm at work today staring at my phone to watch all of CP's friends and my friends' CPs compete and not getting any work done. I enjoyed going to watch the level 5s last year in the arena. Our gym goes to CS, NCA, UCA so I can see any team I wanted to live usually at the other two. I also thought the arena would be pretty empty for the level 4's but there was a decent amount of people each time we were in there. Just my Monday morning thoughts after our competing Fri/Sat NCA experience.
