Yeah, you used to be able to square of that part of the detour by getting off on Warner and getting back on at Harbor, but the entrance from Warner is now blocked also. So when you get to Segerstrom at 6: AM get off and go to the other side of Harbor and head North to the trail again.

I hate these detours, the last one was at Glassell St. While taking that detour I went down and broke my pelvic bone (it was my own inattention, but still!)
