It would be easier for me to list the countries i have NOT been to yet:
Antarctica,
70% of Africa,
Mongolia,
Georgia,
Taiwan,
Sri Lanka
Alaska,
Tasmania
Papua New Guinea,
Most Little Island collections, like Aleutian islands, Kuril islands, Marshall islands, Falklands, Tonga, Samoa etc…
Some of South America (Suriname, Guyana, French Guiana)
There must be more that i haven’t visited yet… but can’t think of any others 
… i want to see all the above at some point… then i will feel content that i have truly seen the world 
I actually have a offline travel blog, if you can call it that… if i ever publish it online i’ll post a link here
