Well, if the question how you COULD do this W/O a takedown, you might look at well-designed bow sling like the one at bowtote.com. Really handy when you need the bow strung and available fairly quickly, but need your hands free...
I DON'T think it would be the answer if you were on horseback, or trying to trek through heavy brush constantly, but in some situations, it is just the ticket.
I have to walk with a cane (walking staff) because of medical trouble. When things aren't going so well, like right now, I have to use two sticks! With no hands left for the bow, this sling is a great help...
A nice retired man designed this model and manufactures and distributes it. May not be your answer, but it is a nice resource for me!
