At Los Cabos

I used to live in Los Cabos for some time and worked here as a boat captain in one of Cabo San Lucas' leading tour companies. Back then, I came for 6 months but stayed for 18. I've done a bunch of things, and visited multiple hemispheres. I traveled and lived in other countries. And now I'm back here, At Los Cabos.
