Was craving some hiking on a weekday and decided to head to Mount Si in North Bend. It's a very short hike, at eight miles round trip, and I got up there with not very much difficulty at all. There weren't a lot of people since it was a weekday evening, but judging from the size of the parking lot, I could tell that this place gets really crowded on a weekend.
I might come back more often just for a quick workout to get to the summit. I might even try doing some running next time; just bought a pair of trail runners (of course, I'd have to go at an uncrowded time)
