This afternoon I was talking with a woman I know from Italy. She had mentioned a month or so ago that she and her husband were also headed to Cinque Terra around a week or two after us so I asked her how her trip was.
Apparently she was swimming in Monterosso (the town next to Vernazza) and got stung by a jellyfish.
So that settles it. I'm never going in the water in Cinque Terra EVER AGAIN.
Screw you Gino.
