The Racing Pigeons Scare A Crow
New Zealand, and especially the southern half of the South Island, has this extraordinary fertile soil. Why that is, is partially explained in this earthcache.
An unknown person once said that you just had to tickle the ground here and things would grow.
Fact is, that this comes with the pleasant benefit of almost every town having outlets where you can buy produce, fresh off the lands.
Such as in Ettrick at the Ettrick Gardens.
