I've been to the Coca Cola 600 at CMS twice, and absolutely loved it both times. Yes, it's loud and dirty, but it's an automobile race, not golf! The facilities are very clean and conveniently located, there are lots of vendors if you need a cold drink or hot food. You can bring your own food & beverages if you want, just make sure your cooler is the correct size. Every one of the staff members that I spoke with were very helpful. We already have tickets to the 2016 Coca Cola 600, and I can't wait to get there!
