eschneid - the seats in row A that they sell for rush are (on the left side) 1, 3, 5, 7 and on the right - 2, 4, 6, 8 - I don't think they sell anything further over than that.
I think the order is front row, partial view, then boxes. Because I always see people sitting in boxes that are definitely NOT students (which was the case today) - so maybe they only sell those at rush if they don't sell them beforehand?
Today I asked for an aisle seat in the front row, and A1 is what they gave me. I like to have an aisle seat, so I typically ask them if they can give me an aisle seat in the front row. And the view from Row A is much, much better than row BB - even though Row A is still technically front row, it's farther back, so you see more. I could actually see Patti's isotoners today.
