I was very impressed with the technical skills of the people there. Belarus and Minsk are advanced in many ways (metro with trains every 2 minutes), electric busses (powered by capacitors, not batteries), mobile phone (MTS shop at the airport sells a $9 SIM with unlimited data for a month), Yandex taxis beats Uber, etc, etc.
The main downside I noticed was meals based on meat and potatoes, not many vegetables.
All in all, I now am curious to find out more about Belarus... Need to spend some time learning basic Russian now!
