I carry about 5 of those el-cheapo rubber hooks in my daypack at all times. I hang stuff everywhere - camera, grunt call, high power bino's, quiver, backpack, bow, etc... Most of the stuff I never even use, but I like to keep it handy.

I hold my bow on my lap most of the day, but if I'm set up with a branch, limb or treetrunk in front of me, then I'm not afraid to hang it up. I don't worry about a little movement too much, b/c I hunt pretty high off the ground, and my stands are usually placed in some cover.
