We have a sweet RV, our life savings and a thirst for adventure. What could possibly go wrong? Well, apparently quite a lot. For starters, travelling with children isn’t all beer and skittles. Then there’s also the logistics of travelling in America as a non-American for a year and finally, once you have sorted the visas, insurances, registrations and local State taxes, you still have to face the hardest challenge of them all – securing a campsite in Yosemite National Park during summer.
