Thanks for the replies. Sorry for the delay, it's been a busy weekend. I'm wanting to unroll in the vertical postion because I will be driving between trees. The fence will be straight in the end. But it would be a real pain to unroll in the horizontal position. I'm thinking of a homemade tow dolly. Something I can slide the roll on horizontal, then pivot to the vertical position and pin it. It would have 2 wheels, and a tow bar that would attach to a receiver ball so I can pull with truck, tractor, or 4 wheeler (or unhook and pull by hand in the tight spots). I know what I want and can build it. I was hoping that someone here had already built something similar.
skyhigh......your method is the way I've done it for years. It would not work well for what I'm doing. I've always cabbaged on to the idea that laziness is really the mother of invention : )
