I won't address the list, but I will the camping questions. If you take a look at googlemaps, there are several state campgrounds along the coast south of Oceanside. However, here in SD I don't think there is! Things that make you go hmmm. So, I'll tell you that yes, there are a few hidden spots that can be found to use and you can contact me directly for them. Seeing as how you're coming from the middle of the country, be aware that 25% of the homeless population lives in the state of CA and SD has a lot of those. So do NOT camp in some city park even if you see others doing it. Your stuff will be gone by morning, no doubt. Along those same lines, I got everything stolen this past spring in Brawley, which is in Imperial County, the next county east of here, so I highly recommend NOT staying there. Should you have any problems, the police would be the last resort (the residents are quite friendly to tourers as it's a bike-thru town on the route east). March is going to be quite warm in the desert (Imperial County and AZ), so be prepared. There will most likely be lots and lots of haystacks in Imperial County where you can sleep next to. I did it on my tour there 3 years ago and again this past spring. Brawley, btw, is the only town in Imperial County with a public swimming pool and showers ($2 if they collect it from you). If you want more info about the CA portion of sleeping under the stars, contact me directly.
