I had to stop the car once because it was threatening to overheat . Pondered returning to the popular trailhead , but decided I wanted to do the hike I came there for , so with trepidation , continued on . Luckily , the road improved within a half - mile . The hike was fabulous . Sometimes when winding through the forest , it seems surreal , it 's so beautiful .
Question: What may be the reason for their hike obstacles ?
The answer to the above question:


They were having troubles driving on the roads .
