Questions for the Author

The novel No Country for Old Men by Cormac McCarthy has left me with a head full of questions, and if i could have a chance to sit back with the author and discuss these questions i would.  The first question being what happens to Chigurh, all we find out is that he gets in a car accident and get severely injured but we do not hear if he gets caught or if he continues to live and terrorize others.  As for question number two i want to know why McCarthy had the gang war in the middle of the desert, and why he leaves some of the group alive and some dead? What is the dramatic reasoning for this is it all to show the brutality of the skirmish or is it just because that is how he wanted to write it.  Finally I would like to know how the sheriff dealt with his grief of not being able to save Llewelyn does he continue with his life as it is, or does he slip into oblivion?  McCarthy never really described what happened to this man, a person that the reader is forced to feel remorse for.
