We visited on the Presidents' Day long weekend, and were lucky enough to do a grounds tour. We took our 4 children aged 2 - 12 yrs. We are not into cars at all, but we found the whole afternoon to be thoroughly interesting and entertaining. Our guide Jason was very knowledgable, and all of our kids loved it. We kissed the bricks like the winners get to, and got to stand on winners podium. Highly recommend this place when visiting Indy.
