there's a couple of serious-looking guards at the ends of the old highway who are telling people to take i-5 until fri or sat. i don't know the details. it has something to do with some ships or something or other.
southbound, there's a hole in the fence and you can go under the railroad tracks and bushwack up to i-5. it looked kinda dubious to me. i was gonna ride back to san clemente metrolink and take the train, but a tourist gave me a pitying htfu look and said she was gonna climb up to i-5 so i went too.
