Their new stand-up bar runs the entire length of the front straight. As such it is IMPOSSIBLE to get a decent seat, if you are marginally disabled, as you have to climb a set of stairs equivalent to about 1 1/2 stories in a building, before you even get into the seats. Then climb further to get to your seats. Being afflicted with both asthma and a heart condition, this came close to ruining the experience in and of itself.
Beyond this, whether due to ticketmaster or the track, itself, purchasing was a royal pain. Not one out of 3 seats was occupied, but when I purchased the tickets, in early February, the seat map appeared to have about 75 seats left in the entire grandstand. And those weren't particularly attractive seats, either.
If you want to sell more tickets, make them all available!
