Hello all; Well, I have screwed myself up and I am sorry. I committed to something I can't get out on Saturday night. I may have = read the calendar wrong and thought it was Full Moon when I said I would be = at a wedding, or maybe I just didn't remember that this was Sentinel weekend. Either way, I need to be back in town on Saturday. =20 So, I am going to Sentinel for Thursday and Friday. I have some observations to do for my book and I need to get them done. I know that = a couple of folks are considering coming out for Thursday, so if your = schedule allows, I will look forward to seeing you there. I do have some extras of the solar system challenge handout, I will pass them on to a responsible SAC member (?) if you need one.
