“Psychologically, we’re social animals,” Hall wrote in his 1962 book Medical Economics, “and there is safety in numbers. I believe that group will survive with fewer problems than will the single family attempting to go it alone. If the father were separated from his family, his wife and children wouldn’t have to fend for themselves unaided; they’d be with other families.”
In fact, Hall believed that between five and 15 families were optimum for a survival shelter. In the event, the idea was so popular in Mount Dora that 25 families committed to the cause. Each of them invested around $2,000, which is approximately $15,000 in today’s money.
