I had a bad day a week ago. Putting up the drywall in the basement and stairway I lost my tape measure. Near as I can tell I sealed it in the wall somewhere, probably with a few other things as well. At the time I had just finished installing 4x8 panels by hand above the stairwell and I wasn't about to remove them to look for the lost measure. Heck I could barely lift my arms, so I resigned myself to buying another one.
That bites, but the next person who buys my house will uncover a real time capsule of construction equipment.
