i wouldn't say 'less than half' - i would say during any given nitro session,
there are maybe 3000 - 4000 campers that are not sitting in a bleacher?
anyone? help? do those numbers seem accurate?
a group i know used to camp just before the last turn-off in shutdown
area - very rarely would any of them walk to bleachers - they tied
a finnish flag to the chainlink fence, as far as they were concerned they
were camped at the 'finnish' line.

many years ago the 'top alcohol camp' was next door to them.
