Just like Australia or other countries in the world the size of the USA puts England to shame and with over 50 states to choose from its easy to be spoilt for choice.
Most people want to do a road trip of the whole country, which if planned properly can be once in a lifetime experience. Alternatively you can travel via one coast at a time depending on which your preference is.
