You’ve gotten a lot of great advice here. So, I’m not going to restate everything. But since you are taking a five year old I would suggest spending the extra money and buy a couple pre race pit passes, and also they have some infield club seating right behind pit road that you can shuck out extra money for. No you can’t see the full length of the track, but you see them scream by up close in the tri-oval and they have a big screen to watch the rest of the lap. The club area is covered, serves food, and is a good space for a 5 year old to run around. Can not stress enough how cool it would be for the both of you to rent scanners to listen to teams talk throughout the race.My five year old has become obsessed with NASCAR, so looking at taking him to Talladega later this month for the cup race. Any tips on seating, parking, etc?
Lastly, prepare for a long ride home. Traffic will be horrible. Please report back after you take him.
