Yes, the hot months are the most difficult to get everyone together... how about early October when things have settled down, kids are on a schedule, it is not quite so hot and humid in the Ohio Valley, and the leaves are starting to turn. Louisville is beautiful at that time.
Also, for most of us, Sunday is a tough time... i.e., church activities, family, etc....
how about a Saturday at a tea house/coffee house/restaurant where we could have a meeting room? Many places have separate rooms for larger groups and do not charge for them... we could all meet and have the tables put together. In fact, I wonder if there is a centralized tea house (St. Matthews, Anchorage, Louisville, Lexington Avenue, etc.) where we would find quieter space? Does anyone have any ideas along that line?
Azalea's is a delightful place... they even have the outdoor patio that can be used by groups (we used it for my daughter's bride's maids shower). They have delightful food and the cost is "average". Something to think about when the decision is to be made.
