Buddy of mine pinged me today about going to the Austin race. I was all in until I saw the prices. Holy cow! almost $300 for general admission and another $400 for a Grandstand seat at turn 11
And I'm not sure you can get a paddock pass either (at least for reasonable money) like you can at one of the European rounds. It's almost worth flying to Belgium, take in the Spa race and have a nice vacation in the region for the cost of a weekend in Texas.
