Commercial earthworms are only 2 minutes away at the nearby Walmart. I'd have no trouble; all I'd have to do is buy some with my groceries.
They are quite small and squirmy but something about that I found enjoyable whenever I managed to catch them. They were awesome to release too because of the way they moved was so liquid and surreal, they looked like miniature flying serpents. Definitely a lot different than my sluggish ball pythons.
You're really making me consider getting one now lol. Here I though I'd be a Boa-or-Python-Only-(Maybe-A-Lizard) guy.
