There are also costs for food/drink (theft basically when you consider what they charge) and added costs if you want to enter the flightline show area.
It is possible to get some good shots from the free area, but not many chances.
It's been a dozen years since I was there...but I remember it being more expensive than the basic entry was!
I was also able to walk right up to a ticket booth and get a ticket for the area at the last minute. That area does have the advantage of seats...after all that walking a seat can be a fine idea.
well, the show is over and i can only say it was great! i really want to post some of my photos, but i have problems uploading them...i'll see what i can do! ;)
