Because they don't care? <shrugs>Why would they do that?
Hopefully there's not a bunch of random junk in the wood chips when I request some. I just need to show my dad the site first.
When I've seen and heard about it, it's not much...makes ya shake your head, but not the end of the world.
You might be better off calling local tree trimmers and asking if they can dump a load of chips.
Chipdrop is a crap shoot, have read of some getting them quickly and some never get anything.
