Yes! Worms work as proven by this sign at Tucson Village Farm. I was tempted to lift the lid on this block trough but I restrained myself. I surmise this is a big compost area where the worms work to turn plant matter into wonderful soil. Check my previous posts on this great health program for kids.
I'm a transplanted New Yorker who loves the Tucson climate. On New Year's Day I have a bit of fun calling my (snowbound) east coast friends to announce that I'm drinking coffee while sitting on my patio. (:
