Newberg is at a crossroads, figuratively and geographically. It is the first city in Yamhill County as you come in on Oregon 99W from Sherwood and Washington County, and it is where you start to transition from suburbs to wine country. Now, Newberg is still part of the Portland Metro area, but still firmly in more agricultural Yamhill County.
As to the physical crossroads, in addition to 99W, you have Oregon 2019 bisect the city on its way from Hillsboro to Woodburn, while Oregon 240 connects to Yamhill. 99W then connect to Dundee to the west, and the infamous Dundee merge that will slowly get better over the next decade or so as the bypass is built south of both towns that will eventually ease traffic to McMinnville and the coast. These roads come with a price though, as Newberg is home to two of the most dangerous intersections in Oregon: Oregon 2191 at Everest Road, which is No. 58, and then No. 43 at 99W and Deborah Road.
All things wine seems to have infiltrated what was sort of a Quaker town over the last few decades. Before that, it was more known as home to George Fox University (of Quaker origin) and was the home to president Herbert Hoover for a time.
