Each day is a grand family adventure with the fathers and sons in this lyrical picture book filled with lush illustrations.   A young son and his father trek through trees and listen to birdsong, dig for worms and go fishing, and enjoy the breeze sitting side by side, just like Pop Pop and Daddy did, years ago.   A heartfelt and hopeful tale that touches on grieving the loss of a loved one as a father and son recreate old memories and make new ones in a day-long hiking adventure.
