Hiya, it was Ensenada Cruiseport. The email is a bit fractured but says (sic) 'please be inform that by disposition of the Port Authority you MUSt have a Mexican courtesy flag raised at all times. Port Authorities will be doing inspections on this matter (date, time)

i don't know what the sanction is, but hey, I'm a guest in a foreign country so I smile and say Esta Bien when told something.

best, Lo
