I have travelled all over America, 33 States if I am counting , there is one constant USPS is everywhere and unusual for a Capitalist driven society, the USPS is kept Federal because they know how essential it is and they also know it will never make a profit if privatised, it would political suicide to do so.
Shame our Government doesn't realise that.
some parts of the US is very remote and I have been to some right remote spots including a few Ghost Towns that no longer has anyone living in them because they are too far off the beaten track and there is no Gold to keep them there, a couple have been preserved with the Obligatory Pony Express post office

no that is a sharp contrast to the overcrowded mega expensive cities such as LA, NY, Chicago wasn't too bad, New Orleans is a mess they haven't fixed much beyond Downtown, outside of it, is like a set from the Omega man, there are some really dramatic scenery such as the Montana in the original post, the rocky mountains is breathtaking, Canada rocky mountains is very striking and beautiful too. I like to go back.
I wouldn't mind being a Postie in either country, Canada is slightly better as they have universal medicare, having said that I prefer my British nationality, unless this country gets overrun and becomes Talibanistan , I would move for that reason.
