My father and I am taking a camping trip in July and August. We will travel for about two months but will tour the United States and parts of the Canada. We have decided to camp because it does not spend as much as vacationing on hotels, but we had to plan carefully. I think the car what we are going to drive is very small, so we decide to take only one small suitcase for both of them and as few camping things as possibly. We will take some medicine with us prevent insects from hurting us, and also some food for picnics. I’m sure that we will have fun.
