Trucker Ray Jersey of St. Louis exercises his dog Samson at a truck stop as snow falls in Council Bluffs, Iowa, Thursday, Feb. 21, 2013. Ray Jersey opted to wait the snow storm out as much of the nation&#39;s heartland is experiencing heavy snow, treacherous roads and a day off from work or school as a large, potentially dangerous winter storm pushed eastward out of the Rockies. &#40;AP Photo&#47;Nati Harnik&#41; <span class=meta>(AP Photo&#47; Nati Harnik)</span>
