Frank,
That is a nice picture.
I there are so many different types of people. I love spear fishing and I was a fanatic when I used to live in Cuba. Beautiful waters and lots of fish. Here I have done some and have my gear at home but can not find the time to do it properly. Now back to my statement, recently I went to a funeral of a colleague. Young guy, crazy car crash, sad,there were like 200 people. From all those people I ended up meeting a guy that is crazy about spear fishing and interested in flying. The following weekend we went flying. Later,His wife complained to me, from 200 people at a funeral, her husband managed to end up talking to the other insane person in the room. We are not crazy, we are just different, I hope!
