In LPNF the Ortega trail is pretty insane right now and Kerry Canyon was a tought one too before it burned over last year.
A bunch of trails in the Piutes
I've found stuff used in Enduros and H&H's out in the open areas that was completely off the hook. Things that made me go "you have got to be kidding me." Some of it I went down and some I passed on expereinceing the pain.
I just considered averything south of LPNF southern Cal. Where is Ortega in LPNF? I've never heard of it.
