Hey Sand, Not in Colorado. I'm a thorough moose finatic, but haven't made it over to you yet. I have my Washington and my Idaho moose. I have to move your direction. My Dad drew Idaho this year, so I get to guide him, something I have been looking forward to a long time. Its time I repaid some favors. Its just been my experience that I've seen more bulls, and they definately respond to calling more. Cows are very vocal, so you can proably track one down by listening to them. Have you heard them in the wild?
