Last year my wife and I went backpacking in the Goat Rocks wilderness along the PCT. We used Google maps to navigate to the trailhead, but had no cell service once we got there. Leaving the parking lot, I decided to see what the built in NAV said, just in case there was a more direct way home. I planned to make the fuel station in Morton with 100 miles of range to spare.
After 40 miles of following the NAV directions, a sign on the shoulder said "Road Closed". Since it wasn't in the road, I ignored it, especially since a pickup truck had also ignored the sign.
10 miles further down the road, a final "Road Closed" sign was placed in my lane.
We had to backtrack, adding an extra 100 miles to the trip and barely made it to Morton to refuel.
Apologies for the stupid dialog and rattles in the video. I put a cheap dashcam in to capture people backing into the car and other crazy events.
