If the date is open, I'd love to attend. I've very much enjoyed all three of the ones I was able to attend.
If I had any preference at all, it would be to have the event in the early fall. Summer weekends fill up real quick with friends and family from the "flat land" coming to visit.
I am aware that is not so good for our "summer only" members, and mean no slight to them.
I also like the idea of an "indoor" venue with access to the great outdoors just in case of bad weather on the date of the event.
