Welcome aboard the RoadTrip America Forums!
As you are no doubt aware, There is an initiative on this fall's ballot in California to split into three separate states: Northern California (San Francisco, etc.), California (Los Angeles etc.), and Southern California (San Diego, etc.). It's also possible that you plan on starting from Baja California. Which of those three potential new states (or Mexico) you're departing from will make a HUGE difference in routes and attractions we might suggest. So, can you be a bit more precise in where you're starting from? And while you're at it, 'Minnesota' is also a fairly big target!
