Staking off or otherwise reserving space in a campground meant for everyone should really not be permitted, it is like someone standing at the front of a line then letting all their friends in at the last minute. It ends up causing a lot of hard feelings and breeds that pervasive "you're not welcome here" attitude that many cite as the single reason they don't come to these rallies.I arrived the day before the rally opened, only to find that two local clubs had cordoned off the only shaded/level camping space and were saving all of it for their fellow club members!
I would hope that a statement noting it is not permitted would be stated somewhere in the rally literature, and security briefed so that it could be stopped before it becomes a problem.
The idea of lanes is a great one, I think a volunteer or two with a few cases of that biodegradable chalk paint spray cans could plan it out in advance and get it done on Tuesday (and knowing rallies we'd probably need a "Please Don't Camp or Park in Lanes" signs as well ). I will not be able to make Oregon, but I would be happy to take this on for 2011.
As for a special spot for the rally chairs to camp, I say that should be the very minimum. These folks come to work, not play - they spend countless (and too often thankless) hours leading up to the rally planning, then spend much to most of the rally working. All for free, all that work purely volunteered and at no cost to the Organization whatsoever. Not only should they be given a specific spot to sleep (with the added bonus they they, unfortunately for them, are always easy to find), they should have their meals covered as well.
