An old site but still fun.
Makes you realise that even though you think you've been out and about quite a bit there's still an awful lot of world left to see. Btw I've only included countries where I've left the airport than been in transit (ie Nigeria, Bulgaria, Thailand, UAE, Qatar, Bangladesh, Malaysia). My visit to the Falklands isn't showing up well and my trip to Tristan da Cunha is completely invisible! Shame there is no Antarctica.
Although compared to my friends and family I "get around a bit", a lot of my work colleagues would put my pathetic travel claims to shame. They regularly circulate the world and would put most of this map red.
