BIL & I were rehabing a single story house a few years back, and rain gutters were part of it. Had about a 10' span we were taking down; he on one end, me on the other. My ladder was too close to the house. Not realizing he'd already pulled the last spike on his end, I pulled the last one on my end. Because I was too close, I was thrown off-balance when the full weight of the gutter hit me, throwing me off the ladder to the concrete. Fortunately, Sparky the electrician was right behind me and caught my upper body before my head had a chance to bounce off the concrete step. I wasn't hurt at all, but Sparky lost his coffee.
I should've known better; I used to do gutter work for a living; just wasn't thinking.
Hats off to you on the gutter work. I've tried installing mine and while they are up it wasn't pretty. Extremely fortunate that sparky was there.
