For months we collected them, in ones and two's, we stored them, loved them, loved them. Then in one night we ... burned them all! Fifty pallets, 11 foot of lovely (free wood). It made a fabulous bonfire - wonderfully aranged by Rob Gimeno it collapsed downwards in a controlled manner and burned for about 4 hours. The one slight drawback was over a billion nails left over but there have to be some downsides in life.
