When I left on the 28th it looked like they were doing final cleanup so it shouldn't be long.
Also while I was there, the 2000 loop was pretty much closed - there was one camper in there most of the week and then they left too - while they were filling in the low areas around the campsites. Then on Monday the 27th they closed the 400 loop and started clearing brush and removing trees.
Thats 3 loops closed at the same time - no wonder it's getting hard to get a reservation.
