The IMS also got a visit from the Colts' Andrew Luck and Matt Hasselbeck today. The idea was to give them a feel for life at the track.
"I think these guys have a pretty good understanding already despite them saying they know so little about it being a team sport. The fact that it takes a full crew not just here at the race track not just during the month of May but all winter back at the shop, guys that work seven days a week to give us the parts that we need, the reliability on the track. Four or five hundred miles at over 220 miles an hour is a very big challenge mechanically, and so the team that's built around us it's as much about their support all winter and all season," said IndyCar driver Charlie Kimball.
"Having lived here approaching a year now, every day you realize more and more how important the IMS is to the city, and how important the whole sports culture is - how the Pacers are doing, us having a fairly successful season last year...the great events that go on here, the great drivers, the racing culture, a lot of the drivers that live in town, how much it means to the city, how much pride the citizens of Indianapolis take in it," said Andrew Luck.
