If your dates are closer to summer you should try and hit some of the Oregon coast. Not sure what you like to skate but Lincoln City is insanity. By the summer there should be a new park in Pacific City just north of Lincoln City. A fun place to drink beer, surf, climb up sand dunes and walk along the cape. Gets crowded though. Salmon River Mouth is one of my favorite Oregon Coast hikes. Its only 6 miles or so but you pass through several micro climates, woods, meadows and finally end up way up overlooking the River mouth. You might run into some Elk and bald eagles along the way.
If you head back East on I84 be sure to take in Mt Hood and Hood River skate park. Lots of cool shit to explore on both the WA and OR sides of the Colombia River Gorge. Amazing vistas, hikes, skateparks, beer, waterfalls, and you can bomb the Maryhill curves....
