I drive OC (mission Viejo) to Ridgecrest every week. Last weekend I stopped in Rancho Cucamonga for the first time and charged to 270 miles - made it to Ridgecrest with just over 100 miles of charge left which should be more than enough to get you the additional 65 miles to Lone Pine. As for Inyokern - not sure what's happening there, I checked in with the construction crew when they were building the charging station in February - they told me they were expected to be done Feb 6, but give it an extra week, no-one seems to know what the delay is.
