What do you do with those boards which are so knackered they're past the point of restoration ? Simple, make a surfboard fence ! Some may think they're artful , some an eyesore, but the smallholding on Maui below has become something of a tourist attraction, with boards being left on the drive for proud creator Donald Dettloff. He now has 400+ and hopes to fence all his land with all manner of floating ( or sinking !) craft.
Keep your eyes peeled for surfboard fences near you; my friend Sean found a perfectly good Vit Sea twinnie filling a gap in a hedge and acquired it for the price of a similar piece of plywood.
