Australian First Time Tailgating

Hey guys, I'm traveling from Australia to attend my first ever NFL game at NRG on Christmas Day, and I want to experience the full tailgating experience.

Are there any tips that people have on how I should go about doing that, like are there areas at NRG that are generally more open to the less diehard tailgaters, and should I bring drinks, snacks, or money? Also, I'm an 18yo Ravens fan so will that make it harder to join in?

Any information helps 🙂
