We use a sled in WI even if there isn't any snow. It still makes it easier to pull. The last few years we weren't able to take wheelers in to drag the deer out so I stashed an Otter sled in the bushes about a month before the season. The Otters worked nice because they're deep and you can hook a bungee strap under the lip on the side.
I did drill a few holes in them though so the hooks stayed put.
