Drive up I5 or 101, find a police station or Dairy Queen and you'll find some world class concrete.
Seriously though, Lincoln City, Burnside are must-dos. Then any Dreamland, Grindline park will suffice...
On I5 I like Shasta (Weed is fun but quirky also), Medford/ Jacksonville, Aumsville, Donald, Some newer ones I haven't hit like Gold Hill and Eugene look very good.
On 101, Brookings, Gold Beach, Port Orford, Coos Bay, Waldport is fun if you want to race around the perimeter and then bomb the hill afterwards, LC, Bay City (lesser known and never skated with a County Campsite right next to it) and Astoria.
Brewpubs are all over. Astoria has two great ones, Fort George and Wet Dog. I like Astoria in general but the park's concrete is getting a little hammered.
What do you like to skate? You'll find it...
