Joey,
Many times I get more satisfacton out of feeding my fish and watching them grow than acually fishing. I think some pondmeisters will tell you the same thing. In NC you could get 3 or 4 more inches by the time the water gets too warm. 3 or 4 inches can really make a difference in weight. Feed them regularly with good trout feed and you will be amazed at how much they grow over the winter at your lattitude. Growth doesn't stop until about 38 F. You'll be O.K. up to about 70 F.
