Some thoughts. As mentioned, a great venue and there's hardly a bad seat in the house from what I saw. Some improvements could be with adding more bridges, although I heard they're building 2 more. Also, acceptance of credit cards needs improvement. When you have $10 beers, $14 hot dogs and $90 T shirts; you need to take credit. There could even be more food stands, as waiting for 40 minutes is a long time.The only other thing I could see was the walk from the shuttle in to the track. It's quite a hike and rather dusty, they should have the 300 busses drop people off right at the track.Like 83,000 people on Saturday and 117,000+ on Sunday, if they can fill the place like this for the next 2-3 years you might see another track built in the US. I was thinking Vegas would be pretty cool.
