     Welcome to the Pacific Northwest, Washington State, the Columbia River Basin, and the Tri-Cities! The spectacular beauty of this region with its diverse agriculture is second to none!

Our itinerary will first take us to Washington State University (WSU) Irrigated Agriculture Research and Extension Center (IAREC) in Prosser, WA, to visit WSU and USDA ARS forage field research and germplasm collections sites. Next stop will be Gauntt Farms, an alfalfa and grass hay operation and exporter in Burbank, WA, followed by a visit to Wagoner Farms, an alfalfa seed farm in Touchet, WA. And, if we have timed our meeting right (we tried), we may be able to witness the spectacular site of alkali bee pollinators at this final field site stop.

The tour will begin with a box lunch as we embark on our 60-minute ride from the hotel/conference venue to the IAREC. Following the tour stops, we will enjoy dinner at Waterbrook Winery in Walla Walla.
