I visited most of east europe countries and russia..and i tell you they are amazing spots and authentic..
Still on my list: china, cuba vietnam and north korea.. becaude they are far and need a huge budget a time.
My dream trip.is the transiberian Moscow-Bejing ..
Countries that lesser interest me are :
Usa , canada, : beautiful nature but no culture or history
france and spain too much commercial turism.
India ( oh boy no thanks)
India may put people off because of hygiene concerns, but if mysticism and spirituality is your thing, it’s a must see.
