10-year old Riley has mixed feelings when his parents tell him that they're moving cross-country. He and his family love new adventures, though, so he views this relocation as an opportunity for just that. From racing on "gigantic slides" and sailing aboard a pirate ship (complete with a mermaid and a cannon) to sipping hot chocolate by the fire and enjoying the beauty of cloud formations, changing leaves, and the setting sun, the family enjoys an action-packed, autumn day in the mountains. All while Riley is documenting their activities in his Adventure Journal.
