1bc1rr,
You may want to check with the forest service before going the I-15 to 138 highway. The last I heard the narrow road was washed out but may be Ok by now. The dirt road is only one lane wide in many places and a 1000 foot drop off on one side. Not for people who are afraid of heights.
You can get their phone # by going to the forest sevice link on the bottom of this page.
Rick,
The fence above the Bradford ridge is more than 1000 feet from the P.C.T. That was where I locked my bike and I never had any problems.
Happy hot springing !
