Off the coast of California is a small island, a few miles across, mostly rock and grassland.
This island was found to be a roosting place for an unusual variety of tern, and ornithologists considered it a place of pilgrimage.
But one year, they arrived to find that the grassland had been planted with grass of another variety – field after field of waist-high marijuana plants.
Upon returning to the continent they felt duty-bound to report this to the DEA, who sent a team to retrieve or destroy the illegal crop.
