I am not looking for a wheeling spot.
Turns out we have interest in a chunk of land out there. Others have tried to access it coming south on Highland Springs only to hit the locked gate at about 33.888993, -116.934030. There appears to be a somewhat mysterious history on some of the adjacent land. None of my family has attempted to access the land. There appears to be some interesting abandoned structures in the area.
Appears looking east from what I think is Petroro shaft (33.8561, -116.9264) is overlooking the subject property. Edit: 33.8565, -116.9381
The most viable path I can see from satellite images and a little bit of internet research appears to be:
10 Frwy
South on Sunset
Left on Shirleon
Right in Old Idylwild
Right on Wolfskil Truck Trail
Left at 33.8561, -116.9264 Edit: 33.8565, -116.9381
Down into a valley to 33.8565, -116.9381 and then foot paths up (South) onto property. I don't see any tire tracks on the subject property.
