Do NOT bike thru the San Joaquin Valley. Sure, it looks all flat and nice on the map, but they neglect to show all the local dogs not fenced in which will chase you endlessly. And apparently, which I'm sure you know, the entire valley is crime ridden. Which I didn't know. Which is why my bike and all got stolen the first week of my tour in Visalia. The other inner route via Salinas I had no problems with. Between Avila Bch and Pismo Bch next to 101 there are basketball courts for sleeping. Have done it twice. Safe tho a bit noisy from the fwy. If you're looking for freecamping for other places, contact me directly.
