That was what was on mine yesterday when the snake pulled out of Traverse City Michigan bound for us. They had said guaranteed for 4:30 p.m. deliver (we are considered rural) but she got her around 12:30 p.m. so I was thrilled!
Crossing fingers your leo's get there okay. From what you said the weather conditions are pretty good (not too hot or too cold) and I've heard they are fairly hardy little critters so hopefully all will be well.
Let us know once they are in and settled.
