This month in my country we talk about "folklore", actually our self folklore.
And how I teach English for the students, I'd like to work with american folklore.
Unfortunately I've never been there and I don't know all american culture yet.
So, if someone can help me, I'll be happy.
Maybe there is some site where I can read something about.
You can start by googling "US Folklore." You will find numerous links, including an especially good entry in Wikipedia.
