It makes me wonder how often he spent time at his grandparents place?
- Did he live there permanently?
- Have his grandparents always farmed/lived rurally?
- What age group do his grandparents belong to?
Sometimes these folk from older, farm-hardened generations are lulled into a sense of "she'll be right" based on their own upbringing and parenthood - that they were raised on farms, and so were their own children, and no one ever went missing. That children Gus' age were always safe and free to roam to their hearts content because they always came home again.
He's been
described by a "family member" as 1. A "good walker"; 2. "shy but adventurous"; and 3. never before wandered far or left family property previously - but if I'm not misunderstood, this doesn't confirm that Gus actually lived at the property he disappeared from.
I wonder if he was very familiar with the property at all...
