Letterbox

Looking after grandson this morning and we had a good time at the Toddler Group and café. Mid-afternoon I handed over to granddad and headed to Killicrankie to see my mum, brother and sister-in-law who are on holiday up there.
We chatted in their chalet and then went to the Pitlochry Festival Theatre for dinner before they went to see the play. I'd decided not to stay on as it would have meant a very late return home and am glad I didn't as I'm tired enough after a hectic week and a bit.
I thought I'd get a blip from around there but it was too grey for anything exciting but as I was going back to the car I saw this unusual letterbox.
