When I was in college and someone said, "Road trip!", it meant freedom and fun. When I became a mom, road trips with the boys were freedom and fun but also lots of preparation and planning. There are lots and lots of resources to help you keep your children occupied while traveling. Try All-American Bingo (I think I pulled this from the Rachael Ray magazine last summer), create your own Bingo game, or a search for "Car Bingo" will give you more ideas than you will ever need :-)
Here are few ideas to create your own Bingo cards...
Dairy Queen, safety cone, mail-truck, ambulance, horse, tree-house, doghouse, canoe, lawnmower, hot air balloon, sheep, fire hydrant, baseball diamond, church, school bus, basketball hoop, construction worker, bicycle, ladder, bridge, tank truck, windmill, taxi, and picnic table. The ideas are endless. This would be a great project for older children. Non-readers? Use picture clues with clip art.
