Dan,
Good for you !! You demonstrated real sportsmanship in making the drive to retrive the bird !
Sadly, there are fanciers who would not make the trip, and IMO, that is a black eye to the sport, when a good citizen goes to the trouble to locate you, and the fancier acts like he could care less.
I have lost several YB's so far this season from actual kills, but 3x's that number from birds that get scattered in a hawk attack panic. Sometimes they do show up days later, but in too many cases, like your bird, many miles away.
Would be interesting to know in the future, if this "worldy experience" helps his racing career, or if the fact that he became lost in the panic is a sign he lacks what is needed.

Due to the very young age and the circumstances, I would be willing to give him the benifit of the doubt.
