one of my "peeves" about the organization is that they don't publish this information in advance. must be "top secret" or something.
IMO, it is one HUGE missed opportunity for the club, to not put this info on the main page of the website. but you will barely find a mention of it there. So many potential new members that might be interested in taking a look.
a few years ago, when the rally was being held in my neck of the woods, I was in the same situation as you. only had a limited time to check it out, and wanted to pick the "best" couple of days. no dice. I even called Jackson Center...they didn't know anything, either.
c'mon, SOMEbody knows what's going on when. It was written down and sent to a printer so they could print up program books. and you know that sort of thing has to be done way in advance. But nobody seems to know who that person is, or where that info might be.
