Hahaha,
I acutally had a cousin who was a former vet and had reached retirement and was often prone to "stretching pennies" he was famous for "mending" fences with old pallets and stretching barbed wire to trees. I don't think it would have mattered if it was next to the house or not, even though he lived in one of the biggest and most beautiful old stone farm houses I've ever seen.
When I first saw this thread I thought immediately of a place I've driven past not too far from Justinetimes where they have built fence (including what I assume to be a roundpen to work horses in) entirely out of the big spools that wire or cable of some kind come on. :
While I don't wish to fence with it, I have often wanted to stop and buy one for a new coffee table in the bachelor pad. <rock>
Stihlpro, not sure what area you are in, but in many places "out west" there are often large quantities of drill stem that can be had relatively reasonable. I've seen fences that were well made from the stuff and painted that looked quite nice and last forever. I'm not sure what the secret to getting paint to adhere properly to it is though as when you get it, it's quite rusty but I know of several places around that have horse paddocks and what have you built out of it and they look great.
