well I can only speak for what has been my experience so far... I didn't find these fruits everywhere.

I haven't found the wild avocados yet. And the supermarket has more california and mexico avocados than local hawaiian ones! Had to find a nice farmers market to taste the flavors. New treat every week.

The "sweet olives" do grow in many places... on hilltops and hanging over roadways. The trick was to find one that was dropping fruit on cleaner ground and got good sweetening sunshine. The Best are eaten on a bright day while the sun is high... these black fruits heat up... 100-degree-hot sweet purple fruit delicacy! Today was such a day. It's like manna. The fruit falls during the day or night, then ripen over the next day, and its too late after that as the bugs get them or they dry out.

Heh, here's some text about the delicious purple fruit from Wikipedia:

"According to Hindu tradition, Rama subsisted on the fruit in the forest for 14 years during his exile from Ayodhya[citation needed]. Because of this, many Hindus regard jambul as a 'fruit of the gods,' especially in Gujarat, India, where it is known locally as jamboon."

"Lord Krishna has been described as having skin the color of Jamun. In Hindu mythology several protagonists have been described as having the color of jambul[citation needed]."

...

I am looking, but i haven't found paradise yet... I'm probably on the wrong island. There is so much potential though; everyone could be growing fruit! They could transform this place. Much of the land here has been abused by cattle, farming, and just modern "life". It could change.

...

I think your passport requirement had to do with you getting on a boat. I don't think I used my passport on my way here.
