Haha Rob, if I'm ever looking up at one and decide it needs to come down, I'll definitely make sure you get a share of the haul.
The seeds came from a guy at the other end of the country who has a dozen mature trees or something. They were planted at least 30 years ago (they are big ones apparently), so maybe they came through when customs was a little less on top of things. I haven't heard of any other confirmed trees in the country.
