I live in Arizona. I had my Az. Mtn. King in the garage for a few months but the temperatures were rarely below fifty. Just doesn't get that cold here, especially not semi-indoors like the garage. I have a male on loan who I'm sure had a pretty good brumation as he's from a much higher elevation (like their natural habitat) and was quite properly brumated. They're together three days then separated one day, and in this cycle, I'll keep them until sometime in June. If she's gravid and has fertile eggs, I'd say it works, and if she's not, I would have to say that I could have missed the window, so inconclusive.
I sure hope it works out. I'm looking forward to my little baby pyros!
