Your virtual rally sounds really cool but a real rally would be very cool. There was talk of activity specific forum rallies a while back. A music or performing arts rally sounds quite animated and entertaining.
Did you have any tentative time frames or park locations in mind? What if you scope out places within say 6 hours from Sacramento and see what choices may be viable for a group of Airstreams with a meeting room or pavillion, the state and national parks have stages or amplitheaters. I prefer outdoor events if the weather is cooperative. (I still can't get over that the WBCCI International parades are
inside, or did I make that up
? 
)
You could also do a member search on the member map or use another locater of the forums' to find members with centralized home bases to your rally.
Hey any Easterners game for such and the same nearby? Cody Bear I just got back from Oregon and let me tell you it was a long haul from here in Michigan. I wish I had gone down the West Coast though, but as it was I was gone a month, not nearly long enough.
Wish the forums had had a get-together at the International, first big rally I've been to that didn't have one.
How about if every unit makes some sort of presentation, whether it be static or live? Get a list going, we've got Uwe for starters.
Actually Uwe how about doing the left side Elvis and the right side Alice.
