We will travel for about two months but                            77.             will tour the United States and parts of the Canada. We                             78.             have decided to camp because it does not spend as much                        79.             as vacationing in hotels, but we had to plan carefully. I                             80.             think the car what we are going to drive is very small, so                      81.             we decide to take only one small suitcase for both of them                     82.             and as few camping things as possibly. We will take some                      83.             medicine with us prevent insects from hurting us, and also                     84.             some food for picnics. I'm sure that we will have fun.                           85.
