I attended the race last year. Indianapolis is very good handling the crowds around the speedway. The best way to enter to the track is come in on 16th street. You can park near the main entrance and purchase your tickets there. The ladies are really nice in there. When I asked if they had any seats left the lady chuckelded and asked me where I would like to sit. My advice is to set in turn 1 area. It has a roof over it and high back seats. Just my opinion. Any other questions just ask.

Not sure how you are coming in but 465 has been under significant construction all summer. Down to two lanes that shift in many areas with uneven pavement. Once on 16th street, however, it should be smooth sailing. Just your normal race traffic. Should be a lot of bike traffic for the race so hopefully cagers will be on the lookout.
Enjoy the race and Hoosier hospitality!
