Paddock Sec 12, Row HH aisle seats 1 & 2. These are absolutely prime seats across from the middle of the pits right by the start/finish line. They are covered seats so no sunburn for you!
I can say from experience these are an excellent area to be in. I can also say that Indy is a hell of a lot more fun in person than on TV. I went back in like '97 and had a blast.
