Watching crews working on cars (this one is Josef Newgarden's).
Seeing cars roll up to the fuel truck to top off before qualifying.
Watching qualifying from Pit Lane means a lot of watching the photographer scrum around the driver who's just about to go out for three laps of fury.
Seeing and sometimes meeting a lot of different racers, including John Force, 16-time NHRA champion (that's drag racing, and he's a legend, maybe the greatest of all time).
Meeting other great people involved in the sport, including these two who run IndyCar's Holmatro Safety Team, responsible for attending to drivers in the case of an accident/injury. They do a lot of good work.
Getting a great view (into Turn 1, from the end of Pit Lane) of the start of the race. You can't quite see it, but the speed trap (red square on outside of track) says the cars are going 214 m.p.h. there.
Getting an up-close view of Pippa in the cockpit of the #18.
Getting incredible action shots of the Dayle Coyne Racing crew servicing Pippa's car during a pit stop. (Click on the photo to see the fuel flying and the intensity on the middle guy's face!)
And even seeing what happens after the race, as drivers debrief with crew and team owners.
