(USAToday) - Tractors still dot the fruit-and-nut themed roads (plum, pecan, apricot) of Canyon County's Sunny Slope, but these days party-themed limousines and weekend wine tourists are also in evidence. Their quarry is a cluster of mostly small wineries with an increasingly big reputation. "We have eight wineries within 10 miles, which is enough for a two-day trip," said Ron Bitner, who recently opened a small bed-and-breakfast at his hilltop winery overlooking the Snake River south of Caldwell.
