I guess she either didn’t have a cell phone or couldn’t get a signal out there.
Correct. Her cell phone did not get a reception.
The article states that she was off of the main road.
She became stuck in sand.
While staying on the main roads, like I do, my cell phone does not have reception throughout all of the park.
Cars go through their all the time going from California to Nevada and back.
I believe that she tried but I have been there and it is seriously desolate.
