Free clean in-fill/soil mix

I'm digging out my backyard and have a bunch of clean dirt in buckets to give away. I have at least 20 buckets ready to go and more on the way. You can also bring a shovel and take as much as you want. It's a mixture of dirt and some gravel so it is not likely suitable for growing but would work for in-fill. I want to keep the buckets so you'll need to bring something to move the dirt into eg buckets or a truck etc. Pickup preferred. Possible delivery in Vancouver, Burnaby, or North Vancouver for a small fee.
