I'm doing it. In my quest to become a living, breathing cliche, my wife and I are taking a cruise next week with my oldest friend and his wife. I'll have internet connection, so I intend to report any goings on that are even remotely bitcoin related. Old people love to talk about retirement savings, so I hope to eavesdrop on many conversations regarding the ETFs. I will try to push self custody instead, but I probably won't get far. I'll also see if I can spend some sats anywhere, but I doubt it.
I'll keep you posted.
For the record, NO sats were spent on this trip. Only filthy fiat!
