We have greatly enjoyed all 3 Coolers. Here's a bit of history for those who are "new" to Cooler and a refresher for us "oldies."
Brwbier proposed the first gathering (kudos to you, Bob!

), and what started as the Eastern Wisconsin Campout, quickly took on a life of its own, soon becoming Cooler Near the Lake.
Early on, there was mention of moving it around, but keeping it in the same general area (Eastern Wisconsin - focus on the Lake), which is still okay by us. We tossed around locations (Kohler, Cliffside, Bong, somewhere in Door County) before finally settling on Cliffside for the first, then Kohler for the second (and third).
As far as the date, that, too, was tossed around, with pros & cons for each proposed date. Conflicts in May (Mother's Day, National Home Brew Day, Memorial Day), then June (ITG2), pushed the optimal date, at the time, back to the end of April.
Which brings us to where we are at now... I think the date is okay...we've talked about this one being the "Teardrop Season Opener" and although it makes for the possibility of unpredictible weather, there's no guarantee the weather will be any better in May.
Regardless of the weather or location, we will probably be at Cooler 4, unless the date should change, then we'd have to check the calendar.
That said...let the talks continue...
