The Society/&Brothers used to refer to them as '3 Day Miracles'! When they realized that the Catholic Church was always talking about miracles too, they decided to refer to them as 'Quick Builds'.
Several JW's were hurt on the job over the years on some of these PR projects. Sometimes when you turned on the light switch, the toilet flushed. Of course, not having any windows made things go a little faster.
Our Hall was a 'Slow Build'! It took us 4 years to finish and is as solid as a rock. Yep, no field service for 4 years!
