I volunteered to help with this, start to finish. We attempted four times. The third time, the chain almost made it to the end, but it stopped on the stairs up to the check-out counter! Setting the books back up after that was a real morale killer, but we had all gathered and worked hard to make this happen, and we weren't about to give up. I'm really glad we tried one more time.
The final fall was complete at 10 pm, and the books were all boxed up by 11 pm.
