No road trip in California is complete without a stop at In-n-Out Burger. Traveling on I-5 from San Francisco to Los Angeles, the 1st In-n-Out is approximately 208 miles south, near Kettleman City. Well, maybe there’s some along the 580 corridor, but who wants to stop there? For diehard In-n-Out fans, there’s an In-n-Out app for your iPhone. Seriously.
