You should always be careful everywhere, but especially right now, on the lower Santa Ana path.
A reader reports that he rode the path Feb 3, 2012, and got mugged and beaten. They stole his Trek Madone , his cell phone, and his bike bag as he tried to ride under the 1st street underpass.
He claims that when he went to the police, they told him that “two other high priced bikes were stolen during the last two days in similar events.”
I’m guessing they have a spotter watching the trail, and as expensive bikes go by, they phone ahead and lie in waiting…
