Three power trowels is a serious setup... how many guys were you running on that rotation to hit 30 yards?

Look, I get that @the_john is trying to be helpful, but are we really turning book storage into a military operation? Plastic bins are a pain to store when they're empty and cost way more than free cardboard boxes. My old liquor store boxes have held up for years just fine.

Holy crap, how did you not notice for that long? Was the glue just not holding right or something? I'd be freaking out about having to redo all that work, lol. What size notch were you using versus what you should have used?
