Last weekend, when the weather was really nice, I spent my Saturday afternoon hanging out with two friends: a skater and a parkour(ist?). I got so many photos, it didn't feel right trying to stick them in with my urban stuff. Consider this a thread to tide your Portland needs over until I have enough to put together a full Portland set.
How did you get the sky to gradient into black like that? It's like its piercing right into space...
I used a circular polarizing filter. They're meant to reduce non-metallic reflections, like shooting through windows. When you point your camera up with one attached, it can really mess up the sky. Personally, I like the effect. It adds a certain drama to an otherwise blue sky.
