Save the weekend of October 19-21, 2001!
Beyond this thread, I'd sent out an e-mail to loads of people (everyone who cam who had e-mail that was entered correctly enough that it didn't bounce as undeliverable)--and the consensus seems to be for October, with a few exceptions. The main objection to October is the possibility of cold, but others prefer October weather (fall leaves, no summer humidity, no mosquitoes, etc.) with only a few conflicts.
I asked the camp if they'd have the third weekend of October available--equivalent to this year--and they said yes! It should be a tad warmer than the fourth weekend. So I've put in for the weekend of October 19-21, 2001. Mark your calendars!
