When I married my wife I married well.  
Our honeymoon was trout fishing/camping in North East Iowa.  She has been to BW before.  I have taken her hunting, fishing and camping.  She knows I have good skills, that is not the issue.  
Accidents do happen and she is worried that if I get hurt no one would be there to help.  I am thinking about a SAT phone to help the cause.
I also have a feeling she may be jealous.  I took two trips this year, then there is this one next year and she has not been able to go.  Maybe if I can commit to a trip with her...3 trips next year...that extra vacation will come in handy.
