Being the OP is from California, I'm guessing Mountain Lakes, Lytle Creek CA. Was there over the the long Thanksgiving Weekend a few years ago and it was packed. Given we have a larger rig, it was very difficult for us to find reasonable site. We won't do that again. Actually, have only been back there once since then. Same experience.
Good Luck.
