Did not do the the actual Summit Trail 150. Went to the summit but approached it from the backside from a park area (not sure of the name). There is quite a network of trails in this area, so i spent some time walking them. Weather was beautiful this evening. "Climate-wise" it was one of the most delightful hikes I've had in the valley. Tried to get a picture of an owl at dusk, but it didn't turn out. Pretty cool though, it was the first owl I've seen close up.
