Thank you, Freecycle! We just picked up two real (as in designed for the purpose) worm bins. And we even got the red wrigglers. Now, along with our homemade bin, we will have plenty of compost and castings. Plenty.
The woman who freecycled the bins told us that she had gotten them for free from the City of SLO. Time to put on the Deerstalker and investigate!
