As I wanted to avoid this becoming a "70% USA tour", I decided a country limit was the best course of action here. Of course it means that for the countries with the largest land masses it would potentially result in a smaller density of covered destinations, but I did this to try and encourage more world coverage.
I don't want this to stop anyone from entering the contest however, so if there is genuinely no other landmarks, cities or countries that you'd want to register, I will allow another US stop since that would still be less than 20% of the overall entries as things stand.
Send me a PM if you want to take part, and that goes for anyone else that is still wanting to register - just 1.5 hours left to go
