The problem is when they say it straight out. The straighter it is, the harder it is to take sometimes. It can make you say and do things you'll regret the rest of your life. It'll make you want to get down on your knees. If the job isn't done when the sun really starts to get up, the EMS guys will go back to the van to warm.

It's true that it's coldest just before the sun comes up. They are doing the right thing. If there is anything to be found, waiting a half hour won't make any difference now. Still, after I've been looking I can't go back with the others. They always feel a need to talk.
