These are some seriously good deals from a $ per mile basis…but with the dollar as bad as it is at the moment, I wouldn't want to be going to the US (last time I went in 2013 the dollar was at parity and I was surprised at how expensive some things were, especially taking into account tips and state sales taxes. Petrol was cheap though!)
