Glad to know you're ok. Question, was that graded or ungraded chain? I've never had a piece of Grade 70 or above fail but ungraded "Junk" chain is just that and I've seen many fail. Any I find I throw out. How far did you drag it on the road? And I'm sure it goes with out saying, a chain is only as strong as it's weakest link which includes all fasteners, hooks and pins.
