I wish the local chippers were so generous here.. everybody here are so greedy as they charge for everything.. if they can sell you a rotten apple they would!
When I was first driving around looking for some free wood chips, I came upon a wood products business that had piles and piles of wood chips sitting out in their backyard. I went in and asked if I could fill up my trailer with chips from their "dump" pile, and was I could for only $60 a load! Well, forget that. Later that day I found my way out to our local county landfill and they told me that they charge the arborists for a dumping fee of the wood chips, but I could come and take as many loads of chips I wanted for free.
