Home at last

My brother arrives home in the forests and mountains of eastern Bulgaria.  A three-day journey from Poitiers seeing family had turned into four days and nights of coach and train rides.  He had spent an extra five hours at Prague bus station while Flixbus sorted out a replacement service to Sofia from where he took a train to Gorna Oryahovitsa.   But then the storm (Debi?) disrupted bus services on the final leg from Gorna to its village terminus so he had to spend the fourth night in the station and catch the bus today.  I suspect that he had to walk the last 12km from Kalaydzhii as he's covered in snow.
