I found last year to be TERRIFIC!! Fun, excellent viewing with a general admission ticket!! 3 days for $90. that is a good deal in my book and I am cheap.
Bring: sun protection as everyone says (hat, pants, sunscreen). Bring a chair and sit on one of many hillsides, move around and enjoy. We tried several places on Friday and a few more on Saturday. Sunday was quite busy/crowded so we staked our spot early and stayed put. Chose the large hill in the center, facing west toward the jumbotrons, place tower, turns 1, 2, 3 and 4.
The cork screw is very 'technical and challenging" but popular/crowded with limited viewing. Check this out friday for practice and get the flavor!!
OK also bring lunch, water, fruit. Then you can also buy from the vendors when you run out. Seriously, even tho you are traveling, buy and bring a small or large folding chair.
We camped and found that to be a lot of fun, good people and convenient to the track. Parking and driving at the track is scary crowded, slow, long lines. (Camping off site comes with a shuttle service!! Wink, wink.)
A good time will be had by all!!! Don't stay home to watch on TV. You can always Tivo, record, etc.
See you there!! Go Nicky.
