Here is Don Carlos our wonderful banana tour guide (and yes the Dole pineapple plantation has a tour guide). He gave us a nice little run down of the history of bananas, they are definitely not native to Costa Rica and like most things they were brought here when development of the railroad began. He is holding a younger banana tree.
This is what a bunch of banana really looks like when it comes off the tree.
In order for the bananas to make it from the tree to the processing plant they take a little train ride. The bananas get covered in plastic and have special rubber padding in between them for transportation to make sure they don't get bruised.
And here are a few of the bananas getting ready to be boxed up and shipped out. The bananas that are singles are most likely going to schools. So there is a really good chance that if you buy a Dole banana that it came somewhere from Costa Rica.
