personally I always used a chair with arm rest and laid the bow across my knee's keeping it always sort of ready!
or when in box blinds as to soft skin blinds, I would again keep top of X bow(foot handle) on a window edge and rest on my knee's like
I am also sure if one wanted to, they could add a HI Bi pod to the bow, to have it just like a rifle one then, laying on ground near your side, a FAST adjustable one, might even be able to be used as a rest to steady things too, like a mono pod shooting stick, kick it to one side like a kickstand on a bike, (w=heel on bow) and should keep it in rather easy reach too!
just make sure dirt and stuff doesn't get in cam and string, a bring a small piece of carpet to lay cam on and that shoudl solve that real easy?
