So is it just as valid as if you travelled to another country, long flights and exotic places or do you not really think of it as solo travel.
I've spent this year doing brief trips around the UK - which is 4 countries but all feels like home - . or is it one country? A lot of wildly different landscapes, different traditions and different local foods and having a great time.
The USA is huge and even more different place to place. In fact this applies to many countries that have very different areas within.
So is it cheating/not solo travel unless you have to fly, encounter foreign currency and another language.
