There were lots of old rusty nails sticking out all over the place in a spot right next to my daughter's playground, so I decided I'd better do something about that. Without a truck readily available, I decided I'd just remove all the nails from the lumber and make a pile of it somewhere until I had an opportunity to take it down to the wood recycling place.
As I was pounding nails out of boards, I realized that a lot of the pickets, posts and stringers, while not in great shape at the top or bottom, were in relatively good condition for most of their lengths. After disassembling a couple of sections of fence I had a pretty good pile of cedar that, while not any good for building furniture or houses out of or anything like that, were still solid enough that the idea of just sending them away to be chipped and mulched kind of grated on me.
My mind began to churn, what could I build out of all that still perfectly serviceable wood? I later on decided I'd rebuild that entire fence and pulled down even more boards, until the pile got really big. I settled on structures for my garden, and this instructable was born!
