Before you set off for this Nano cache, get yourself a toothpick or paperclip - you will need it to remove the tiny thin log paper from the Nano.
The Nano is magnetic, and is attached to something metal - the hint tells the full story.
Please do not park in the bus stop, it will draw unnecessary attention from angry bus drivers, parking is simple and ample just around the corner on The Grange Road.
Please make sure that you put the nano back carefully, and put the cache back together as you found it so that it is not cross threaded.
