Establish your way back to Your Friends
For "Concert Tips and Tricks" - if your group is going to be in the center
of the arena floor, count the overhead lights to give yourself "coordinates"
so that you can find your way back from the restroom or whatever.
When you get inside the concert hall, decide on a place where you and your friends can
meet if you get separated. We always have lots of concert-goers coming
by looking for their friends.
Thanks to Noodles for this tip
