Donnie,
My opinion is that you didn't work him hard enough, long enough and gave him one too many breaks. If there were lunch wagons/roach coahces on FI, the chances of finding him near there would be highly likely.
Too much, too little, too soon! Be a tougher, more disciplinary tyrant with him next time. He'll thanks you for it in the long run and you can be sure if there is ever more turf to lay around there--he won't be with-in 200 miles of it!
