Wallcrawler, Not sure if I would be a help or a hinderance - she might not like to hear from anyone who would leave home for a month!!
For me personally though, I know for a fact that my passion for hunting has made me a better person. In my younger days I spent time in bars, and hunting made me give that up. I quit smoking cigarettes to save money for hunting and to be able to breathe in the mountains. Although I could certainly do more, I work fairly hard at getting in shape by riding bicycle and hiking in preparation for my annual trips. I still carry more weight than my body needs, but it is certainly less than it would be without hunting.
Treat her well, and devote extra time to her needs the rest of the year. I don't get away with hunting as much as I do by arguing with my wife, but by her understanding of how much it means to me and how deeply it stirs my soul.
