Took a short hike out by the North Fork of the Snoqualmie River. Nothing exciting out that way - some decent views, some decent hiking, but not nearly as exhilarating as the South Fork (along I-90). But we had fun, of course, including a picnic lunch on the tailgate of our car.
We caught a glimpse of a waterfall in the distance, one I'm pretty sure has no trail going to it (this is a couple miles north of Mount Si and don't know of any falls that have been marked in that area with a trail map). This fall is about a mile away and we could hear it.
