Packing and Planning

We have been planning this trip for about a month.  I want to go visit my grandma in Minnesota, see my brother and his family in Denver, hit the Grand Canyon on the way and Mount Rushmore on the way back.  We started doing school work at the end of July in order to prepare for a three week vacation without getting behind.  We have started the countdown.  The kids are super excited about the trip and about seeing their cousins and second cousins.  I have been cruising many travel websites trying to find things to do to break up the long driving days.  Hoping it all goes smoothly and I don't decide to sell the car along the way and fly home!
