Dylan frowned as he watched the "No Signal" text on his phone blink. 

"Sorry, I don't either," Dylan said. 

A cacophony of "Me neither," "not me," "I don't either," rang out. 

Mrs. Staffer said, "Alright then. Don't worry guys, I used to drive when all we had were plain old maps." She laughed and Dylan knew that it was likely every student on the bus was rolling his or her eyes. Probably even some of the chaperones. 

"I bet she was driving when the dinosaurs were still around," Dylan heard a kid say. 

Dylan snorted and whispered to Josh, "Yeah, because I'm sure there were busses around at the same time as the dinosaurs millions of years ago." Dylan realized he was probably taking the statement a bit too seriously but things like that irked him. If someone was going to make a stupid joke, it should at least make sense. 

"There should be a map under the seat, Kally," Ms. Mindy said from the back. 

"Wow," a girl said from one of the seats in front of them, "look at the fog."

Dylan looked out. The fog had been light, but now he couldn't see anything at all. At least before he had been able to discern trees passing them by, but now all he saw was a wall of fog. He placed his hand against the window. He thought he could feel the spot that he touched grow colder. The fog seemed to grow thicker near his hand. He heard something that sounded like a whisper and he shuddered.

"Did you hear that?" Dylan asked his brother, looking back at him with his hand still up against the window.
