Plans for a new Cumberland Farms store in Cranston are being met with resistance by some city residents.  The gas station and convenience store would be located on Park Avenue near Edgewood, with seven buildings needing to be demolished to make room for the business.  Opponents say the store will be out of character with the area, and its presence would harm area businesses.  The chief supporter of the plan is Mayor Allan Fung, who says the location is blighted and in need of new life.
