Wish you the best of luck on your show. I know how those stage gitters can get. I was in a band and would get nervous previous to every show. Just remember to relax and most importantly to breathe.
We stayed in Houston during Ike, which wasn't as bad as I expected. I thought it was amazing how strong nature's force can be. Although they repeatedly tell us not to be near windows I couldn't help but watch every so often. It just took your breath away of how the trees would bend as if dancing. Of course you can't mess with nature, but its always better to be safe than sorry.
