This is sweet!
Wow, I've never seen a chain gang of hydrants! I am curious why they're in such close proximity to one another.
I'll confess that they're actually not in use - they're set up as decoration outside of a local dog grooming shop, I guess so dogs can pee on them as they enter or leave? There's actually a bush shaped like a poodle next to them.
There is a conspiracy going on here
