WELCOME!
The flag is a signal to Stewart that we are with him every step of the tour (or as many shows we can coordinate the flag to). It is a green flag which Dirty Martini constructed and it has the above left Stewart Polo logo on it. The people who take it to the show have a large responsibility to:
A) Have perfect timing and wave it so Stewart can see it at least once.
B) Not be an 'asshat' and tick other fans off around you by annoying them with the flag and/or obstructing their view
C) Sign the back of the flag, and not get carried away with using too much space (like I did in Miami! oops)
Here's a link which will drown you with info about the flag and proper flag behavior:

PS) Are you in Alabama? Gulf Coast? Just guessing from photo. I'm right next door, um Atlanta that is!
