You can use it in pots again or just dig a hole and bury it.

Find a friend with a garden who could use it as a soil amendment, or spread it in a neglected flower bed somewhere, or pour it all in a bag, stick a sign on it that says FREE GOOD POTTING SOIL and leave it out by the curb...all kinds of possibilities.

I tried bagging them once in a garbage bag. They get very very heavy before I even fill 1/4th of the bag. I dread it breaking in my living room as I am hauling it.

Thank you.

LOL on the movie clip! Great film, that.
