Get a MONEY BELT and put a few THOUSAND of your currency in it.. in large bills.. then just cash them in as needed. In AmeriKa you have to go a any ban with "NATIONAL" in it's name.. AmeriKans are very backwards and immature about traveling so they don't have banks that can exchange foreign money like you find in the CIVILIZED WORLD.
I'd say cash or card. Bring like 200 cash and the rest on a card.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
