Well, PenWAG isn't that group.
Sure, it's almost all women (now, before we joined it was all women), and many of them "are of an age" but they're definitely imaginative and have a sense of adventure.
We found the meeting in the Immanuel Lutheran Church's fellowship hall. There was a table of snacks and a big pot of coffee just inside the door, and people starting to gather in the meeting room.

We handed out a lot of Costume-Con 26 fliers.
The day's big event was (instead of a workshop) a meet-and-greet game. Members were asked to submit stories and facts about themselves that other members weren't likely to know. There was a prepared list of items, and the trick was to match each fact with a member. They included things like "I used to be a carrot breeder" and "After graduating Phi Beta Kappa from an Ivy League school, I went to work as a waitress at a GI bar." One of the members is the General Counsel for Apple, Inc. (got to remember to drop "computer") and another developed the monitoring and control systems for the life-sciences experiments on the first shuttle flight.
They bring in local and national workshop presenters, and often have limited-attendance workshops which should provide some real quality time with the instructors.
If you're at all interested in textile arts, I can highly recommend this group. Meetings the second Saturday of every month (unless rescheduled).
