Has to be said: Wheels can/do compact soil and disrupt ecosystems. Tracks can be seen for decades after a single ill adapted vehicle passes. I have seen such tracks turn into washes when the rainy season comes around.

Narrow wheels highly loaded cause more damage than wider ones lightly loaded. The forest service rules on no wheels is far easier to enforce than debating the vast unwashed masses who would seek to comply the letter of the law while violating the spirit. Forest service vehicles are typically ATVs using large and wide flotation tires that usually cause less damage than a person walking as long as they are driven responsibly.

A travois is a viable choice but the FS guys will object as they leave tracks that can last for a century. I used one in an exercise. A handy way to move a load too heavy or bulky to carry. A sapling with the majority of limbs left on can be used as a crude travois and saves time because you don't need to limb a larger tree to make poles.

Come the first of the year you can play with discarded Christmas trees as a sort of field-expedient travois. Tie a piece of one inch webbing to the butt as a harness. Pulling the tree is quite easy. Depending on your strength and their weight dragging several kids on top of even such a makeshift travois can be easy, and quite entertaining for the kids. Moving several hundred pounds is not an unreasonable undertaking.

Something to keep in mind if you ever have to move someone, or something, in the woods. Note: cutting trees is usually frowned upon but you are pretty likely to get a pass in a real emergency.
