Well, that may be because you don't stand on the field during the game.
When I go to an airshow I don't sit on the runway, either.
Stuff happens.
Where do you think the box seats are? Out on the runway?
The A row seats are maybe 50 feet (max) in front of the grandstand. The B and C rows are closer. The attraction of the box seat area is you can bring in your own chairs, your own food and drink and have a party with your box and all your neighbors. It's also not as uncomfortable as the stands.
We aren't Sheeple, as another post said. Nobody forces us to buy the tickets. We don't blindly wander out onto the active part of the runway or taxi ramp.
I wonder how many posters here who are knocking the races have even been out to Reno in September...let alone Stead airfield during Race Week?
