+1 for skip diving in all it's various forms.
Like Kittyhawk with his wife, my wife tends to walk away from me with a "He's NOT with me" look on her face when I used to do that stuff.
I say "used to" because now, with all the public dumps for scraps of all types that we have here (not just skips), it is "streng verboten" to hook any stuff of any sort out of them. And many of them in supermarkets, etc, here are now built so that you'd need to be an Olympic high jumper to get inside! (I'm NOT BTW)!
While I can understand the economics of this approach, especially with scrap metals the price they are these days (not to mention sheet wooden goods) I do firmly feel that we're taking away the possibilities for youngsters to learn to repair rather than just dump stuff, AND overall, I wonder if we're doing any long-term favours for the environment? "We" cannot just go on and on making new stuff for ever surely?
