Luckily, three Mustachians did go to the meetup, and had a good time.
As far as I know, no one brought or passed on any colds. Fresh watermelon was shared, also chocolate chip cookies, perched on cool limestone. Family talk and personal stories bubbled around while other users of the park bounced basketballs and picnicked. Bits of finance mixed with occasional adventures in work from the perspective of our Mustachian band and a variety of other stories. By the time dusk brought our conversation to a close, everyone seemed interested in continuing and adding to the new tribe - by meeting again, maybe next month.
One thing mentioned was that some of the commenters had wished for a week day instead of weekend day. Possibly some people will do only one or the other; maybe we could alternate.
So, would anyone who wants a weekday (or weekday evening) meetup like to step up by proposing a day in early October?
