Well I do remember now(it was too early in the morning when I posted before, and I hadn't had my coffee yet.), Bruce had an exchange student who helped with his chins too. I believe for exchange of room and board, the student had to help care for the chins. It's been years, but I remember meeting the kid once, pushing a broom in one of the buildings, and Bruce explaining who he was.
As for Jack, I do know his daughter (and grand daughter) lived next door and did care for the chins if he was away.
There was never too long of a time (i.e. days) where the chins went without someone looking in on them or cleaning their cages, or caring for them.
For him to come to the BC shows, it was a short trip, and he was back home. He would show up in the morning to judge our shows, and he might sleep over, but usually he would go right back home over the Coquihalla.
Even then I believe he meant, if he said that to you, about having it set up - as in that his daughter didn't have to clean cages or do any work other than look in on the chins, and check the waterers and feeders. That is what he had explained to me. It's the same as what I would do if I am gone for a while. I would clean cages, and set everything up so that it wasn't too hard on whomever is looking after them.
You're welcome to call and ask him, if his daughter looked after the chins while he was away. He still lives there, still the same phone number as always.
The only thing truly set up for a week, was perhaps his automated watering system since it hooked directly to his house... but even then, his daughter still had to check the waterers to ensure they worked. She still had to go in and check on the chinchillas. I know that, because I had asked him too, whenever he came to my home on the island, for a few days. Same with the shows.
You might have met his grand daughter, as she did the paper work at some of the NCBC shows here.
