So the girls got over the pass thanks to the wonderful truck driver who helped them put on their chains. Then a light came on in the car. Pull over to the rest stop. Get out the owner's manual. Bad light to be on. Then the car would only run in reverse. Okay, really bad. Called AAA. 1-3 hours, understandable as 3/4 of the state was in a state of weather crisis.
Tow truck driver arrived. Got the car loaded up. Then a lady, in distress, came along and asked if he could help get their car back on the road at the rest stop's entrance back onto the highway. Tow truck driver said okay. And he tried, bless his heart. Turns out they were in a ditch. And..... tow truck eventually ended up in the ditch too with Daughter's car on the back.
Tow truck driver had to call a tow truck.
(The Engineer picked up the girls where they left the car to be fixed (2 hours from here) and they all got home at 11pm. A five hour trip turned into 15 hour trip. Eldest, DIL and Youngest will try the trip on Wednesday!)
