Pine Bark Fines

I'm preparing for next year's container gardening soil.  Part of the mixture is referred to as pine bark fines which is basically ground pine bark.  I've read a bunch about it on the internet and it's benefits, but I'm not going into that today.  Instead, I'm showing you how I procured some in an attempt to lower costs.  Yesterday, Donovan, who was in town on Christmas holiday from college, and I went driving around.  I literally looked for downed pine trees.  Well, found some and loaded up as much as I could find.  The pic below shows the amount gathered and the end result after I ran it through the shredder--3, 18 gallon totes.  So, my efforts garnered 54 gallons of crumbled pine bark.  A good thing.  Next, I'll go to Home Depot and get a couple bags and compare to see if I actually saved some $$ or not.  Any way it goes, it was worth the effort to me.
