Please let me know what you might be interested in. In late August or early September, I will post an itinerary for the event. Weekends under consideration are the Columbus Day wknd (Oct 11-14) and Veterans Day wknd (Nov 8-11). It worked quite well at CM Phx in the Spring where those able to come a day or more prior to the weekend did so and participated in things not on the schedule.
Feedback is always appreciated.
