Feeding animals can be tough work. Feeding the animals of the entire St. Croix Valley can be even more difficult. But that's what the new animal feed store River Feeds in New Richmond is trying to accomplish. The store opened up over Memorial Day weekend, but has been in the mind of owner Pat McNamara and his wife, Terri, for a long time. "He has always been very enchanted with the idea of a feed store," River Feeds Business Manager Emily Reed said. "He's wanted to open one for 20 years."
