Hi,
I dive solo 99% of the time. First on OC and now on CCR. I prefer to do it that way. I'm also the only one with a rebreather on the island.
I frequently get remarks about it from new people on the island, but I just say "thank you for your concern" and jump in. I only do shore dives here, so I don't have to deal with boats and companies.
Just two days ago:
new girl on the island: "are you going diving alone?"
me: yes
new girl on the island: "but that's not allowed"
me: really? didn't know. Who says?
new girl on the island: "I don't know, but it's only allowed in Egypt, not in the Caribbean"
me: oh, really, and by which authority, then?
new girl on the island: "I don't know, I just heard it"
me: ok, well, have a nice day, I'm off diving
Most people know me here though and don't criticize it.
