If I may; Correct Chris!
The camp ground was full by Wednesday Evening. At 2100 all "non cars" where turned away & sent to alternative camp grounds on the south side, around where the railroad crosses the road going past just up from the main camp. At 2300 the camp was a; overfilled & main gates closed. Uncertain how they handeled this in the two other camp grounds.
Things cleared up by late Friday-Saturday.
I came in on Tuesday early morning & there where quite a few cars on the ground already.
So if You want a prime spot, Wednesday is simply too late unless You have someone roping off for U.
I BELIEVE they started removing "tape" already on Wednesday afternoon....
I did not feel it was THAT cramped... Then again I was camped very close to the entrance....
