Sharp Tail Snakes, Backyard, Sonoma County

Three of em. I'd never heard of this species, in its own genus, with a protruding final sharp vertebra (hence their name) they use to pin down their favorite meal, slugs. I let them go in some wilderness nearby. Lockdown silver lining: who knows if I ever would have seen one of these if I hadn't been spending more time in my (increasingly obviously awesome) backyard?
