"Loud" doesn't do justice to the sounds of being at the track.
In 2013, my wife and I were guests of Chip Gannasi Racing at Texas Motor Speedway. We had hot passes, use of NTT's suite, the whole nine yards. Jamie McMurry was their cup driver, and this kid named Kyle Larson drove their Busch car. We got to meet them in the suite.
My wife stayed in the suite all three races while I was in the pits for the truck and cup races. During the truck race, I stood next to Dave Blaney, whose son, Ryan (maybe you've heard of him?), won that night. Sat in suite for the Busch race. During the cup race, I stood next to Jimmy Johnson's pit (first pit at entrance), who went on to win the race. When not racing, had free access to wander around the pits.
If you're a big NASCAR fan, you can bid on hot passes through the NASCAR foundation's website (or at least start there). I highly recommend doing so at least once.
