Jack and Peter hold the map of the woods and hills behind Graddad's house in Maine. Granddad maintains the system of trails as part of the state snowmobile trail, and in the winter he negotiates a big grooming machine along the twists and turns; we borrowed his little Kubota dumptruck, and managed to get it stuck in the mud. We're obviously city kids, though by the end of our week in Maine, Jack and Peter were old pros at following the trails and were no longer quite so concerned about my trail-driving abilities.
