I belong to an online yahoo group that has a retreat once a year or so and a small guild that has a once a year retreat.
The online group goes to a private hunting lodge during their open season. I think this group is limited to 24 because of the sewing space.
The small guild goes to a church camp after camping season is over. This group is limited to 18 because of sleeping space.
Both of them are a whole lot of fun.
I think it would be great to organize a retreat or two for people on this board to meet and have fun!!
