A seat if you are not going as press
and plenty of money for food.etc.
Get there early to get a good parking spot and be warned, getting out of the car park at the end of the show is a PITA!
The Warbirds are usually parked at left of the showground and if you are there early enough, you are allowed to walk around the flying warbirds and talk to the groundcrews.etc. You may get a glimpse of the US Army assets parked on the ramp behind them
Fast jet assets fly from the NASA ramp at the right of the showground. They try to taxi everything past the crowd very close up atleast once.
For an idea of what to expect, check out my article from last year. Really wish I could make it again this year, the press officer invited me back too! http://www.airshows.co.uk/reports/overs ... r-houston/
