Since we launched the toll free version of our Ask Sam hotline, 1-844-GO-OTTER (844-466-8837), we've seen a real healthy uptick in queries. This time around we decided to ask Chris Martin of the New Hampshire Audubon, and Dave Anderson from the Forest Society to join Sam in our quest to answer your questions about the outdoor world. We've got everything from the geometry of wombat feces to planting trees by the light of the moon. #AskSam
