A1 : The following editorial appeared in the South Fork Gazatte.

“Last year, the city contracted with Flower Power to plant a variety of flowers in big decorative pots on Main Street and to water them each week. By midsummer many of the plants were wilted. This year the city should either contract for two waterings a week or save money by planting artificial flowers in the pots. According to Flower Power, the initial cost for artificial flowers would be twice as much as for real plants, but after two years, we would save money. Public reaction certainly supports this position: in a recent survey, over 1200 Gazette readers said that the city wastes money and should find ways to reduce spending.”
