Big Ouch!
I can sympathize with that. ‘Bout 35 years ago I missed my step and plunged through a fiberglass patio cover onto my 10-speed bike and then the concrete slab 10’ below, right onto my knee!
I can almost hear that concrete against your knees! Hope those knees recovered OK!
Not only did Sandy hit things and break things...he drove himself to the hospital! One VERY determined individual!
