The rush seats are located in the very back of the orchestra. (Mine were Row V i believe.) It is obstructed view, which in this case means you cannot see the top of the stage because of the overhang of the mezzanine. I still found the seats fine, and was not too put off by the "obstruction".
P.S. They are very strict about the time thing in the rush policy.
