You can watch but i need to know if you want to crew as you need to have a champ car membership plus be signed up through the registration site before the race.Oooo, if i have some free time I'd like to come down and watch! I could help crew if you needed/wanted.
Watching from the paddock or trackside building is free from what ive been told and doesnt require prior registration you just cannot come into the pits.
