Seed exchanging in geocaches

[Mango_Seed]

I have never geocached or exchanged seeds, but I wonder if they might benefit each other in combination? Some sites might work as seed exchanges. Some sites might work as plant a seed or seedling and lets see if it survives? Some sites night be small food forests and might get bigger and more nice using a geocache. I don't know? Just an idea I had a last week.
