I was at a thrift store last week and passed on a two story, chain escape ladder. Yesterday, I was thinking that I could have just shortened it and kept it in the bedroom to hang out the window in case of an emergency. I think we could get out of the original slider with practice. The only thing is that I know my wife would never try it.
I will say this, smoke is a great motivator to get someone who would never consider it, to jump out of a window.Here's hoping you never find out. Cliff
