Going to be in Portland for a few days during NYE (Friday - Monday night). I've been to Portland before for a conference but did not get to see the surrounding area. I was thinking of taking a day trip somewhere Saturday, but wasn't sure what the best option given the weather, and possible road conditions/closures etc. Some things I was considering were driving to Columbia Gorge + visiting wineries around Hood River, taking a trip to Willamette Valley for wine tasting (are wineries open Saturday?), or driving down the coast. Any advice?
