They have made a very serious decision--they are going on an adventure. All by themselves, just the two of them. Dad might offer a suggestion or two, but this expedition is just for them Of course, they will have to bring coffee and pickles and blankets and a cozy tent. And, just in case, a jump rope to use as a lasso. They set up camp in the lee of a small mountain (or, in their backyard) and get ready for an evening of fun. But when the pickles are gone and the mosquitoes come out, what's to be done? The Grand Expedition is the quietly comic story of two kids and their dad and the everyday adventures that make life great.
