I coould reminisce all day....
When you got to Checkpoint Bravo you had to approach the Russian soldier with your documents and salute him, even in civilan clothing(something never done in the Army). Before approaching however, usual form was to leave a can of Coke and 20 cigarettes near your front wheel as a 'treat' for the Russian soldier who checked your vehicle. To him, these would become prized possessions.
It was surreal, being the only time you would ever come close to a Russian soldier during the Cold War.
As you say alba, a different world.
