Took a GnR down the basement stairs with my son below and me above. I had moved dozens of machines with him in this configuration. For some reason, I thought, maybe if we lay the refrigerator cart flat on the stairs it will slide down easier than one step at a time. I said, "are you good"...he said "yes"..."are you sure"..."yes"...so I lay it down and the next thing I know it is following him down the stairs (in a hurry)...I thought I killed him. He was wearing sandals and he caught one on the other and slid down the stairs with the GnR following him. He was OK and I was relieved for both him and the GnR...all good. But he has been hesitant to help me ever since. I now have an Escalera and all is good.
