I've heard from quite a few people at this point (not all, please weigh in!) and this is where we're at now:
23 June -- bad for Jolene & Kristine
30 June -- bad for Jolene & Kristine
7 July -- #1 for Chris, #2 for Jolene
14 July -- #1 for Jolene, questionable for Chris
11 August -- #1 for Kristine, questionable for Jolene, not possible for Janine
Jason, Jessica, Heather (contingent upon moving plans), my parents, and I are game for any of these dates.
So that's how things are shaping up right now. I didn't initially ask about later in August or Labor Day weekend, but maybe those would be just as good for people? Send me feedback via email or in the comments here, and we'll try to figure this out!
