We were in the Crown Lounge when we went through the fog. We have had several cruises with the horn being blown for fog. And, they've all been out of Baltimore. It's Maritime law when visibility is below a mile or so. Nowadays, with radar and AIS, it's not as necessary except in the case of small vessels (private mostly) but it's still required.
We found out why the debarkation basically stopped for 1/2 hour or so. CPB called for the stop. Once they started up again, it went really fast. We had a family member pick us up and we kept texting him to delay him. Finally around 1015, we got off and he was there about 5 min later to meet us where Lyft/Uber were picking up. Of course, the angle of the gangway didn't help this morning. We were b2b and last weeks debarkation and embarkation went a lot smoother/faster. As b2bers, we were off through customs and back onboard by 1020 or so.
