Why one? I have surfed 40' swells in a yacht off Durban and been to over 30000' as pilot in command of a single seat sailplane. I've soared the mountains with vultures. Driven the Makadigadi salt pans and the Okovango. Watched a sunrise at sea. Been shot at, several times! Changed countries of residence.

I can teach you to sail, fly or program a computer. Pick one, two or all of them!
