This should be a quick find just off the secondary highway. No need to cross any fences, and there's a rarely used access road a few metres to the west to pull onto where you can park to make the snag. Don't worry, the muggles in the yellow house have been told to expect the occasional visitor (we know them, they're cool).
Keep an eye out for thistles, there were a few in the ditch when we placed this one.
