If I recall the prices for the full event were about, the pilot pass $40, the spectator pass $20 & the tent camping pass $60, the RV camping pass was a bit more as the RV sites were a bit larger than the tent sites. Both the tent & RV sites are primitive, no water or electricity. They also had day passes for those who could not attend the entire event.
The cost has gone up just about every year. This year we get an extra day of FF so the full event prices even more.
