It's the same situation here in SC. The best option is to have a couple of young, able-bodied fellows at the ready. Outside of that, I've used nothing more than a rope to drag many out.
I once tried to use a kid's snow sled. It worked great on flat ground, but not so much on steep hills. Going up, it would want to slide back down and the lack of friction made it a constant battle. Going down hill, well, you better hang on. A 200 lb load in a slick sled can go amazing fast on pine needles.
A friend has a fancy one wheeled cart, but using it is definitely a two person affair. Four is better. His does have a brake on it and a big wheel, so it rolls over logs and such pretty well. It is huge, though. We never tried it on really steep terrain. It would be difficult on some of the steep stuff around here.
I'm looking at getting a Game Sled. It's got some built in handles and looks to be a pretty tough material.
