I'm sure no one has done this before, but I was working on something big and awkward for my brother that was taking up room in my shop, finished the project on Sunday and loaded it in the back of my Ranger by myself, this thing is basically a 6' wide 3pt work platform thing that has to weigh around 200lb... I leaned it against the tailgate and tried to push it over but it was digging into the concrete and wanted to tilt so I just did what I had to do to get it in... somewhere in the middle a part of my lower back got warm... now it hurts to stand for more than say 15 minutes and sometimes my left leg has some numbing pain thing and is very distracting... so, yeah, that's the most recent dumb thing I've done... should have taken the 10 minutes and rolled the A frame over and lifted it in...
