I couldn't help but smile (and then feel guilty and sympathetic for the company and the loss they must have suffered) when I saw a news report today on the Cruise Liner that had issues at it set off on its voyage, and is subsequently having to refund all of its passengers. Ouch.
Mercury of course relates to travel and in Cancer (water) it seems too good to chance such a trip. I'm sure travelers may heed the advice of this period in the future - it's not the best time to be scheduling major trips.
For reference, the Titanic set sail when Mercury was retrograde.
