Well, it looks like I'm going to have to close the two polls below. It's not just because the responses have slowed down, but also because the poll service I signed up for neglected to mention that they weren't really a free service after all, but only offered one-month free trials.
Anyway, it provides as good an excuse as any to move ahead and try to do some more planning. It looks like Labor Day weekend is the time most people can get together, with Columbus Day weekend close behind. Let's get a discussion going in the comments about which weekend is better for everyone. If we can nail down a date that will help those who need to make travel/vacation plans well in advance.
And expect more polls here soon. And maybe this time they won't disappear after a month.
