Wear comfortable shoes, chances are people will be lining up days in advance if they can, or at least very early the morning of the show just to get as close as they can. I am debating on heading up from Seattle, may wait for the 2016 stadium leg as they probably will play Seattle at Century Link Field again. They have seem to start/finish their tours in the past here in the NW, so perhaps Seattle could either be the start of the 2016 leg or finish up the entire tour here, all speculation of course.
I'll be honest, based on the stage layout being thrown around... a Main Stage and b-stage
