I'm planning a trip from SF most of the way to LA in late March. I'm planning to take the inland route, including Soda Lake Road and Elkhorn Grade through Carrizo Plain. I've seen various blog posts about riding there, but I'm wondering if anyone here has done it? I'll be on a road bike with 28 mm and am experienced riding on dirt, but I'm hoping the roads in Carrizo aren't excessively sandy or loose? Thanks for any intel.
