Cal is great for camping but the speed limit blows and so does your fuel prices. Left Oregon a month or so and paid 3.29 for diesel and got to CA and it was 4.19. Add to the fact that everywhere is packed to the gills it's just not worth going there anymore. Sure we'll go back but not this year.
The official speed limit towing in California is 55 but its more like 70. Yes, our gas prices suck! You can still find lots of places to go camping in the summer and the winter. In the winter, we go camping in the desert (Death Valley, etc) and in the summer, its the Sierras (yes, there are plenty of places in the Sierras that you can get even without an advanced reservation).
I work for the Navy and I often camp in San Diego when I go in for work but I live up here by Big Bear. I get the best of both worlds!
How many other people can say that they can be in the mountains and down at the beach in just over hours???
Also, California has a bad reputation as being a "police state" and lots of crazy, insane people...well kinda. However, when you go camping, you run into many more like minded, good hearted people who love to camp and enjoy the outdoors, just like everyone else. Just my two cents.
