I don't think I was "badly mistaken" but I did kinda goof on the Borrego Springs as your recommended site listed it by a campground name (that many of us never really knew - only knew the place by state park; that is the way it is generally referred to)that is in the State Park. RVPR shows it by the state park name.
I do not know what you mean but sure can't find it much easier than this - go to the state, zoom into the area you want and click.
Also, each time I go to your recommended website my Webroot and other preventative measures warn me it is a dangerous website - that is scary. Hence I will avoid it.
To each their own.
