I'm going to one about 25 miles away in June. It's just an overnighter but Carol Doak is going to be there. Threads and Beds (part of the LQS, Threads of Time) has open retreats once a month, we just have to register ahead of time and let them know when we'll be there. We can stay overnight, several nights or just go for the day. The also have other "specific group" retreats that are closed to the public. It's great though to have the fabric store just on the other side of the door. If you run out of thread or need a fabric it's right there.
