For those of you in colder climates, when do you usually start to bring your tortoises outside? I'm in New York, and even in the hottest part of the summer, temps aren't regularly in the nineties, let alone in the spring. Should I bring my tortoise in for part of the day to get those high basking temps? I want her to get as much natural sun as possible, but I'm concerned about it not being hot enough for her.
