It's almost Poppa's birthday and young Theo wants to give her beloved grandfather the perfect gift. Poppa has traveled the world and keeps a trunk full of mementos collected on his adventures. That gives Theo an idea for a very special gift: a new adventure! They'll take the streetcar to the local beach, sink their toes in the sand, skip stones and stop for lunch at the beachside cafe. Together, Poppa and Theo plan their trip and sketch a map of the route they will take. That special map, and the memories and keepsakes of the day, will join the other cherished mementos in Poppa's trunk. At the heart of this story is a charming family bond. Rich storytelling captures the magic of turning a simple outing into an adventure. And spirited illustrations will keep readers engaged, inspiring them to create their own adventures --- and memories.
