You’ve not got Uganda on that list – so not worth going!!
Loved Peru – Ecuador good too… Go to the faulklands, just so that you can say you’ve been (apparently there is fuck all to do there!) Cubas apparently awesome.
In terms of the states – apparently there is a company which either pays you, or gives you cheaply, a car to drive accross the country – for those people who move house to an opposite coast, and dont want to drive across the country – could be worth some research.
