Solunar Calendar

I recently spent some time with a friend who leads/teaches survival classes in Montana.  He tipped me off to this Solunar Forecast for hunting and fishing.  Supposedly, it is designed to inform hunters and fishermen of optimal times to catch their game.  I haven't had any experience with this, but hope to give it a go this season.
