I was just there a few hours ago. I use the SRT to get to Marymoor and then do a Lake Sammamish loop. My favorite ride is 202 out to North Bend and back but it’s dangerous. 55mph limit on a rural road and an 18 inch shoulder is not a good combination. Someone was hit and killed on 202 last summer. Sammamish loop seems a lot safer. Low speed limit for cars and a really wide shoulder for us.
