The original topic was about whether the park boundary or roads are correct. Sorry for not being clear on that point.

Given that choice, the roads and trails seem to be correct, and it's pretty close to the USGS 3DEP data (great for seeing below the trees). I'm saying that the current park boundary in OSM is *likely* incorrect, and those boundaries seem to be like the CPAD data instead of the California Parks data.

While I could go figure out how to correct the CPAD data, getting the data out of the California Parks service and into OSM or CPAD seems too difficult to pursue. There seems to be ways to go contact both sides and get them to talk to each other. Though the current copyright message on the CA Parks data would likely require legal council in order to do the right thing. Involving a copyright lawyer, and my lack of data import abilities, exceeds my level of interest in helping. Maybe the next person can do better.

In any case, thank you for all your hard work in the area.
