My buddy has infield passes and talked me into going for a race weekend. I'm not a NASCAR fan — I watch F1 occasionally but that's it.
Bro. The energy at TMS is something else. The sound of the cars at full speed literally vibrates your chest. The camping scene in the infield is like a tailgate that lasts 3 days. People were SO friendly.
I didn't follow the racing strategy at all but the experience was worth every penny. If you've never gone, go once. You'll get it.
