Shooter,
I would pretty much agree with Paul Richards. The holes inside the track are pretty cool atmosphere wise. There are a couple of others that are OK, but way down the list of Indy must see courses. A friend said he was out there playing one time when they were doing some testing for the IRL or something and he said that the noise was extremely distracting but the cool factor made up for it. Could you imagine the pros trying to play with that going on in the background?
