Someone has build a cave in the hill next to our house...

Yes - strange goings on in the hill next to our house.....for those of you who don't know Rich and I live on the top of a hill up a big flight of stairs (if you're coming from Aro Valley anyways) and on the park of the hill just beyond the stairs someone has dug some holes (one so big it's covered up with boards!) and cut out a track to access said holes...it's slightly worrying - Rich went and investigated the scene today and we are sure it's nothing to do with the council because there are no signs or anything up....it is a bit worrying....oh well we will have to keep an eye on it and see what else happens...
