You can get a fold-up trailer from Harbor Freight for something like $250 if you get a coupon online. I think there's a cheaper, smaller version, but I've beat the crap out of the one they sell that's 8'x4' with 12" wheels. I pull it with an Accord, and it's hauled more branches, manure, and random lawn waste than you'd believe.

You have to put it together, but the cheap self-assemble trailers work, if you can get close enough to your hunting area.
