City of The Dalles officials plan a ceremony Friday morning to officially transfer ownership of the Elks Building to a developer planning to establish a neon sign museum there.  The Dalles City Council, acting in its capacity as the Columbia Gateway Urban Renewal Agency Board, approved purchasing the building for $240,000 and then turning it over to developer David Benko, whose group agreed to do an estimated $1,000,000 of improvements to the new building within two years to get the museum open.  The Portland Art Museum is taking part in the fundraising effort for the museum.  Mayor Steve Lawrence and Benko will sign the agreements for the deal on the steps of the building on Third and Court in downtown The Dalles Friday at 9:30 a.m.
