This night footage is absolutely beautiful. I'm happy they speak English on your radio stations because I'm from the USA hoping to move to Zambia in the near future. I only speak English.
Glad you are considering Zambia as a possible destination. When are you planning to move? You will be glad to learn that the official language in Zambia is English and as such, you will NOT have difficulties interaction with people: the average person you bump into has some conversational English speaking skill. Best wishes as you plan your move and do let me know if you need help and feel I can assist!
