It is a country that requires no vacinations to go, it has a very good infrastructure. Roads can be rough, but public transportation is definately available. We stayed in Grecia and used it quite a lot to get from our country side lodging (see escapeincostarica.com to see it).
You should be able to talk to Richard or Mela, by the way, about that place we stayed. $175 a week! $450 a month!
While I leave room for things to change, it is a bargain! Hope this all helps. Hope I can be of further help to you with some hubs I'm developing on the subject.At hubpages.com/hub/Costa-Rica-the-inexpensive.
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.
