A listener recently asked, “Has the entire surface of earth at some point or another been covered in poop?” Turns out, there are some questions that even we can’t answer. 

In this installment of our regular mailbag segment, the Outside/Inbox, we do our best to take on your zany inquiries, or find experts who can. Here are this week’s questions:

• Why was there a sudden spike in “dangerous carbon monoxide levels” during a snowstorm in New Hampshire?

• Is there any official recognition for hiking the Appalachian Trail, Pacific Crest Trail, and the Continental Divide Trail?

• Why are live scorpions allowed in the mail?

• Why do kids (and adults) chant “Do it! Do it! Do it!” and other chants?

• Do all predators have forward-facing eyes?

Featuring Kathleen Simmons, Carlos Santibanez-Lopez, and Barb Lake.
