I live by Inglewood Hill and E. LK Samm and last summer I came up with a great 25 mile loop. I ride the E. LK Samm gravel trail to Issaquah then up to the I-90 Grand Ridge trailhead... up and over.. then down to the bog and up to Duthie. Fart around Duthie awhile (at least a couple of hours!) and then it's a 5 mile "road ride" back home. This year, however, I need to get rid of as much road riding as possible. I'll be on the lookout for a good connecting point on the SE side of Souring Eagle... with that I can make this an almost all dirt ride through the suburbs!
