Dally directs the boys to Windruxville because

Dally directs the boys to go to Windrixville and hide-out. He knows of an abandoned church there where they can stay out of sight.

"Hop the three-fifteen freight to Windrixville," Dally instructed. "There's an old abandoned church on top of Jay Mountain. There's a pump in back so don't worry about water. Buy a week's supply of food as soon as you get there--- this morning, before the story gets out, and then don't so much as stick your noses out the door. I'll be up there as soon as I think it's clear. Man, I thought New York was the only place I could get mixed up in a murder rap."
