Would you be leaving your retainers in camp? I'm not sure about leaving a camp unattended. Sounds like there are sketchy people about. :\
We could still do that with the mule and cart, though. Since there are multiple forests sepatated by hilly grasslands, perhaps we could leave the mule/cart/camp/retainers in the grasslands, returning at night? Still might be unsafe for them though.
I was thinking that pack mules, while less able to carry stuff, would offer much better mobility - we DO have to cross a river.
Moving forward you see about ten small village hunts and a couple of barns ahead, build near a large stone bridge that crosses the Moktone River...
