Glendale SX will mark the first truely dry race of the series. Inside the University of Phoexnix stadium will also mark the first race in a venue used primarily for football.  That means the longest start straight of any race this year and very long rhythm lanes.  The whoops are also the biggest. The riders and teams spent a lot of time looking them over. They may be the part of the track that can make or break your qualifying time.  Check out some of the early morning pit action and the track walk.
