I'll admit I've taken my snakes into stores, but it's usually say, on the way home from an expo or coming from the vet. But they're in a pillowcase, sitting in my bag. And I don't let people know that I have a snake in my bag. I'm not leaving them in the car.
X2 I may be bending the rules but i dont wanna risk leaving my snake in the car with high or low temps. And what people don't know won't hurt them.
