That's crazy! May be true here too, but I got permission from a manned transfer station and scored a lot of copper bus bars.

Yes but read the signs or get permission before taking anything!
Here in The County of Los Angeles (and I'm told most of a California) it's illegal to "steal" from the drop off bins, eWaste, curbside pickup (trash cans), or transfer stations. Believe it or not people have been arrested for "stealing" from the trash cans on pickup day...
