The Denver Fur Ban is a succinct title for a ballot measure. But opponents of the November initiative say its effects will be anything but simple, and they prefer to wrangle with specifics when they make their points. Initiated Ordinance 308 — which seeks to prohibit the manufacturing, sale, trade and display of select fur products — would have a raft of consequences that go beyond prohibiting retailers in the Mile High City from selling fox and raccoon fur coats, those opponents say. It also could cut into the inventory at fly-fishing shops, people in the angling business say.
