Hmmm... I'd say that Sunday the 15^th would be a good day, except that we probably won't want to wake up early after the party.

The following Sunday (July 22) is also probably good, as is the 21^st. I presume that we only have weekends to work with, yes? I'm on vacation but I don't want to presume that anyone else is. However, if any weekdays would work, let me know because they could possibly be fine by me...
