I agree but usually $100 a trailer to park at a Grands is for a week, 1-3 times a season and may come with some services such as power, trash removal, etc. When $300 is charged for parking it is usually for Vendors that are coming to make money or support their products & services. To charge $100-$300 per trailer to park each race for up to 15 events, well that can make a person think twice about going.
Just like in Politics, maybe we should have a "Occupy Free Trailer Parking" or "Parking Tea Party" and just all park in free parking. I know I could use the extra excersie walking to & from the track.

Happy Super Bowl Day (Go Eagles!.....next season) Looking forward to racing the 2012 "Gen Next" Series.
