You guys must like to do a bunch of walking, or don't get in too far. If we're going in far, we use a pac 'orse, if you remember those, work well on single track. We put our packs on it and pack in in the dark. If it's a road, we usually take bikes. We ditched the 2 wheel carts years ago, too much of a pain. If we get an animal down, and there is no cart with us, we bone it on the spot and load up our packs, maybe coming back with the cart depending on the terrain.
That being said, I don't think I've used the cart in about 7 yrs.
