In this Thursday, Feb. 20, 2014 photo, Yolanda Tolentino-Reyes competes in the first-ever women's division of the annual Napa Valley Grapegrowers' pruning competition at Beringer Vineyards' Gamble Ranch in Yountville, Calif. Pruning is an important part of vine husbandry that focuses the new growth on vines and helps determine what the next harvest will look like. Different techniques are used for different grapes and climates, and skill is as important as speed. (AP Photo/Eric Risberg) less
