My wife and I went to Crab Flats this past weekend. Fri-mon.
We have a 2015 powerlite 24fbxl. And a Tundra Crewmax. Stayed in site 6. Took 2hrs from San Gabriel Valley. Clean camp ground. Water connection at #5. 35* At night 70* daytime. It was an adventure once you went from the main paved road to the dirt road as you turns left. But that was half the fun getting there. We have Sprint and got good cell signal. Bring plenty of firewood. Open from May 1st - last weekend of Oct.
