Does anybody have a good idea approximately how many tents there are at Pennsic? Do you think it's safe to assume that the ratio of tents:people is reasonably close to 1:1 (what with dining tents and storage tents, vs. tents with more than one person in them (and folks living in non-tent structures)) or is my guess regarding how many people share tents too low? Will the US Air Force (or Army, or whomever it is that uses us for photometry and reconaissance practice) tell us how many tents they counted? (I've heard they check the attendance numbers to find out how well their population estimation algorithms work, and that we make a rather convenient test case that way.)
