What an amazing show sunday night. I was in te third mezz and when the guests started coming out I had no idea who they were until bob introduced Elvis Costello, then the mezz went crazy I stood still for a couple seconds durind FOTD and I could literally feel the floor bouncing, it actually made me a little nervous, but the floor shaking started my legs moving and before I knew it I was dancing right along with everyone else!Thank you boy's for puting on an amazing show.

The way that place is designed the balcony's had to be built to be able to flex, with that long span and not having any supports in the middle. But yes it does get some people nervous, your not the only one.

Also read the thread "hey Yall" to see how the guests came about, Phil talks about that along with another very exciting idea that is going to be happening.....

sorry for the double post but the thread im talking about is actually called "hey, gang"

Thank you I read the thread and edited my post.

the balcony was bouncing too

You may never realize it but all bridges and parking garages are made with that same concept. Without the play in it the concrete would crumble haha. If you ever notice when your going over a bridge you keep hitting breaks in the road every so often. These I think are actually grooved spaces in between to let play in the bridges construction. It's weird

they are called expansion JOINTS
