Yeah limerock is a great place too. Very family friendly, they allow walkthroughs to see all the cars in the pits(some race teams will let kids sit in the cars and give free stuff), they allow camping, and it's just generally a nice place for people to go who enjoy motorsports. My only complaint is IMSA and some of the bigger events can be pretty pricey, but I do understand they have to keep the place running so it's minor to me.
