One of my favorite movies is Fandango...ever seen it?  It features a really young Kevin Costner and Jud Nelson among others.  A group of college friends set out after college graduation on a road trip to dig up a bottle of Dom Perignon that they buried years earlier.  They make frequent stops along the way and encounter crazy characters and just see the country!  I love it!
My huband and I took several weeks two summers in a row long before marriage and kids and just drove.  We went from GA to West Coast and back and saw whatever we wanted to see.  We tease and say "That was back when we were in love!"  We miss that freedom!
If you are lacking the freedom to just take off and drive, or if you just don't have the time or courage to do the road trip thing with small children like my husband and I, check out this game called Discovery Channel® American Road Trip

It can help you show your children the world until you can muster up the energy and courage to take a RoadTrip yourself.
Summer is coming to an end and the heat is unbearable so pop some popcorn, turn down the lights, and have a family road trip from the comfort of your couch.
Enjoy!
