Hey folks, just a couple of notes that might be helpful:
1. I live in San Jose, and the sections labeled 120-124 are always the sections behind the main stage at the Shark Tank (as we call it here in SJ), no exceptions (though there's certainly a first time for everything).
2. They never sell tickets for these sections at this venue unless there will be no backdrop behind the main stage. I've seen/heard of many acts doing this no-backdrop thing.
3. This all leads me to believe that the Red Zone will be next to the B Stage, and that the main stage won't have a backdrop.
4. Of course, I could be wrong. Just some guesses based on my own eXPERIENCES, as it were.
