When I have extra logs, CL helps me get rid of them quickly. When I have extra rocks, I add them to existing drainage or retaining walls. I always need more rocks and less logs, I guess it's a Pacific Northwest thing...
Ditto, ditto, and ditto...in the same county as you. Were you giving away logs a month or two ago? If so, think I saw your ads...lol.
OP: If you're willing to deliver them, I bet you'll have a bunch of people game to take them. If you're willing to have a bunch of random people coming over and cherry picking a few bits, you might get rid of some or most of it over time.
If I were you, I'd take some photos of it on the ground, then one of it loaded into your truck or trailer for perspective of size/quantity. Place a CL and/or FB ad for free, saying it's loaded and ready to drop off within x-miles radius of (your location) today or tomorrow. If I were me, I can think of a bunch of places here where I'd use the stuff, but I'm guessing you're on a small suburban or urban lot if you're trying to get rid of stuff like that.
Considering that a 15-ton load of crushed stone can be purchased and delivered in a nice pile where I want or tailgated out where I want for less than $350, I don't generally spend the time to drive somewhere and manually load rock, concrete, etc. unless it's something special I particularly need. The return on my time is pretty sucky if I save $23 to bring home a ton of something. Long story, short...make it easy for someone, and I bet you'll have a person grateful for the fill.
