If you wanna travel to a legit beach then head to Tahiti, that is one awesome place, and if you like surfing hit up Bali and Australia. I agree that doing things when you are younger is great when you have no family responsibilities, but seriously if anyone thinks you can't do exciting/adventurous/crazy/exhilarating things when you are older (i mean 30+) you are nuts. Shit i boarded in Las vegas before xmas and there was a skier who was 92 tearing up the mountain.
Im not 30 yet but i plan on doing shit like surfing snowboarding skydiving hiking snorkelling scuba etc etc etc until i die. And as far as trying to leave a mark on this world, thats what i think is LAME just do what makes you happy, anyone who is trying to be extreme or adventurous so that others remember them that way is missing the big picture, live your life the way you want cos it makes YOU happy (and your wife/kids/family), don't live it to be remembered.
In doing this you will probably be remembered more for your personality than your actions, Just my opinion thats all
