Greetings Google Researchers!

I"m an artist and I"m seeking resources (i.e. surplus stores, web
shops, junk yards etc.) through which I would be able to obtain items
such as:  old barn wood, rusted piped, rusted fasteners (screws,
washers, etc), rusted cogs, fan blades, wire....that kind of thing. 
anything that looks distressed or rusty and can be me made into garden
art.

I live in the Los Angeles/Orange County area of Southern California.  

I'm looking forward to your answer!
