Plan Man,
I would say you are due for a visit!
One big change was that they widened a couple hundred sites, made them all concrete, and (naturally) increased the prices. These are the Premium sites.
They were made "big rig" friendly. The original sites (and current Partials, Preferreds, and Fulls) have 12' wide concrete with a sand pad at the back. The Premiums are 18' wide concrete sites with no sand pad (paved over) and flare out wide at the road to make backing in easy.
Oh, and they expanded loop 600 almost up to the front door of the Meadow Trading Post (a travesty IMO).
What kind of trailer/rv do you have?
