Hi!
I was travelling by bus from Poland to Zlatni Piasăci (near Varna) about two years ago. I remember that some time after I had passed Sofia, I saw a huge monument by a motorway interchange. It looked like a two-toothed pitchfork (Y-shaped) pointing east. It was some kind of sign-post - one of the tooths had rusty letters saying "ВАРНА", another "РУСЕ" on it.
I was travelling by night, so I don't know where exactly that interchange was located But I searched on Google Maps and found a Sofia-Varna-Ruse interchange in Veliko Turnovo.
Is there such a monument in your city, or is it somewhere else?
