COLUMBUS, Neb. (AP) – Nebraska plans to offer a record number ofdeer hunting permits this year to help control the growing whitetail deer population.     More than 250,000 antlerless deer hunting permits will go onsale Monday afternoon along with several types of unlimited buck permits.     The Nebraska Game and Parks Commission expects deer hunters to exceed last year’s all-time highs of 141,000 permits sold and about88,000 deer harvested.  Officials hope to reduce the deer population by 25 percent in some places to reduce crop damage and deer-vehicle collisions in the heavily populated areas along the Missouri and Platte rivers.
