Well as long as you can keep track of it and you want to take it go ahead. I have a nano also and love the thing. I probably won't take it hunting though.

I bought a case for mine I like alot its a clear hard plastic case that still lets you use it. I have it in my back pocket all the time. It protects the screen and the whole case. You may want to think about that first. I got it at Walmart for about 15 bucks. Other than that I don't see why taking it would hurt anything. I generaly like the sound of the woods more. But at work or at the gym I listen to mine alot.
