Another exception is the Oregon Coast (where I grow up) It's bright yellow but pretty much no one lives there (relatively speaking). For example, the county I grew up, Lincoln County, is roughly the size of Rhode Island but has only around 45,000 people (figures from memory).

But it is extremely touristy. Highway 101 grinds to a stand still most summer days, especially when it's really hot inland in Portland / Salem / Eugene.
