Earlier quoted context omitted.
Look at the map, they were told early on where to go and went in the opposite direction towards the fire, though the text skips over this without explanation as to why.
We got different advice from different rangers. One ranger on the phone told us to hike out. Another ranger on the ground tried driving out and told others to follow of she didn’t return. The opportunity cost of trying to drive out was low. The fire’s eastward progress was slow so the hike out would still be there.
Glad you made it out ok.
