Those who have not been to a retreat and want to go, might adjust their profile to give a hint about where they live so they can be notified or invited to join one in their area. I know the Virginia QBees have tried to arrange gatherings or retreats a couple of times and have had some trouble locating other QBees.
Retreats may be a day long or many days long. Some are full of sewing; some have a few other activities as well. Some are really expensive; others are much more doable cost-wise. Some have instructors brought in; many just have the participants doing their own projects. There's something for everybody in *some* retreat, somewhere!
