I will ride in the dark almost anything, even single track, but I am an experienced mountain biker too. In CO I ride in and out in the dark on a single track. I wear that flashlight the wensel's sell on my headband, it lights up the world! Well worth it and the batteries last almost a whole season of elk/deer hunting.
My bow is a take down, so I strap it to my fanny pack, and then just wear the whole thing. You have to dress down and carry some clothing though because you will get warm in a hurry. I just take my time and use caution, walking where it makes sense due to conditions and not wanting to fall on my quiver of b-heads.
