It really depends on the cost. I am tight on the budget but all of it sounds awesome. I have not done any ski diving or kite surfing as of yet. All else you listed I have done quite a lot. In any case I have travel America to every state and am really looking for sailing adventures and going to Europe. If you are looking for sailing crew I would be interested but depending on the cost involved. I am on a budget and this is a 1 - 2 year depending on funds used adventure. From my experience it is difficult to find folks that do so many different sports and have all the certifications and want and have the funds to take off work and do it all. But if you are looking for sailing crew let me know. It would be a blast. thanks ERic
