If none of the above work for you (and I’d take them to the Sallies or similar) they’d make a great water wheel - wired on to an old bicycle wheel. My dad’s collecting old pots for one himself, hampered only by my mother’s habit of finding other uses for the pots.
I think I will try to donate it to a domestic violence shelter as recommended by Oakminster. Failing that, it will go on craigslist. I feel better knowing it won’t be taking up space in a landfill quite yet!
