Feeding the ducks and geese at local Boise parks, is it illegal?

Since this is not the purview of Idaho Fish and Game, we checked with Boise Parks and Recreation; it is illegal to feed ducks and geese in Boise Parks.  (Chapter 13-03-02 C. 2. in Boise City Code prohibits the feeding of birds and waterfowl in any park). For other towns, please check with local city authorities.
