Red Dead Redemption Q&A

How do I save the game?

I have two questions:
1) how do I access the items menu? I don't know how and it's driving me crazy.
2) in which area do I catch the Hungarian Half-breed horse? You know, the white one. I have the other two stallions and I only need that last one.

Can any1 tell me where twin rocks is i hav been looking and i cant evr find it now tht im done with the campaign

Looking for the population signs for all towns. Where are they?

Are snakeskins worth collecting?

Basic ally, like, can you make anything with them?
