Ah, yes, obviously I know where this is. He is back in Chur (on Ottostrasse), where he stayed on Friday. He may just be on his way through because he is not in the hotel. How I know? Because my husband ... called again.
Will I rush to Chur on a train now? No. Because I am pretty sure he is already gone. He may be going to the Jungfrau region next ... It's a lovely drive to the West, over the Furka-Oberalp Pass.
