I'm on the road as you see this, heading to Monterey, California, where I'm moderating a panel at the annual Organic Produce Summit (OPS). (One of my panelists is Richard Gonzales, Vice President Global Produce Sourcing for Walmart … I'll have more about this later in the week.). But being in an airport, particularly at a time when air travel can be totally fugazi, I'm thinking about business lessons that can be applied to retail.
