May I suggest Peacock Lane in SE Portland?

It would be a bit of an outing from where you are, but the four-block stretch of lights on both sides of the street is really lovely, and in past years they've had caroling and a canned food drive set up.

I used to live ten blocks from there, and made a point of going every year. If you do decide to check it out, I hope you enjoy it!
