Having read Joe H's "The 5,000 Mile Hamburger" in today's General Food Topics, I am now sure that my husband and I must share the experience when we visit California in May. We'll be landing in San Francisco,then driving to Yountville to spend a couple of days, then back to S.F. for a couple of days. Please tell me there's an In-N-Out somewhere in the area! And advise these first-timers on how and what to order.
