On Saturday I was at DCA and was watching WOC in the wet zone of yellow. I had an alright view- I'm really short and there was a tall man in front of me around a foot taller, but I was able to see what I needed to see... until he picked up his son (who I assume was around 8 years old and pretty big) and put him on his shoulders. I ended up leaving before the show finished because I literally could not see a thing. I didn't tell him anything because I didn't want to seem like a jerk- but he probably wouldn't have been able to hear me over the music.
I totally understand wanting your child to be able to see the show. It's a bummer when your kid can't see anything. But when you put a child on your shoulders, you instantly ruin every single person behind you's view. It really upset me since this is the only time I'll be able to see WOC (this was my first time at DCA, but I'm moving to the east coast in a few days). It's so inconsiderate to block everyone else's view.
So, why not hold your kid like this?
The kid will be able to see at the same level as the adults around them, and won't obstruct a person's view. This is where the rule will come in. If your child is above your shoulders, you will be asked to leave or to move to a section all the way in the back. This way, if you want your kid to still be on your shoulders and have a better view than everyone else, you have to stand behind everyone else, so no one is behind you.
