This Old Man (Nelson/Marlborough) Traditional Cache

I've wanted to do a cache like this for a while. It's a traditional and should be just a park and grab for most. Once you've done this you can go and get BigglesNZ's Airport Walk. A busy road so beware the muggles. 

I'm not giving too much away about this cache because I think it's going to be pretty easy. If you've parked opposite an address with an emergency number then you're in the right place.  Just approach the first old man you see. Only room for a log here so bring your own writing thingy.
