"While rescuers didn't come across the yellow rain jacket strips tied to trees during their search, Karen Peterson of the Daggett County sheriff's office said Grayson was still smart to have done what he did..."

Ditto to UncleGoo. Although he might have learned how to build a shelter from Bear Grylls, that seems like the only thing he did right. In fact, it says he got panicked and left his pack, probably the only tool he had to help him survive. (It would be interesting to know what was in the pack).

I don't mean to be harsh on him because I doubt I would have had the sense to do anything right as a 9-year old. But giving Bear Grylls the credit is a stretch.
