Glad you are OK.
We all need to keep telling these stories as they happen so the rest of us get it through our heads that all it takes is one second of bad luck, and in-attentiveness to get hurt out there.
As you all saw me report last fall, two commercial strap on steps broke under my weight and I came straight down....maybe 4' only, onto a stiff leg, right on a main root that didn't give...and I though I broke something for a while. Unlike above...NOTHING went thru my mind cause it was over before it started. Scared...you bet. And I only fell 4' or so.
Please be careful everyone.
