Why all the rails?

Visited y’all for the first time against the Preds the other day and no one in the arena could tell me why every row in the 300s has railing in front of it. The internet comes up with nada except maybe it helps ushers identify who is leaning?

What’s the scoop cause no other barn I’ve been to has this? Very unique for sure.

EDIT: Yall are awesome! The mixture of factual dialog and hilarious banter was the exact thing I experienced at the game itself. Also this taught me about you alls long history of hating this viaduct plan and the ongoing attempt to demolish them and rebuild the area, keep protesting yall!!

Also, I’m jealous of your Costco being by the arena, clutch meal choice.
