I will be traveling from Kansas City, Mo to San Francisco, Ca. This will be the first road trip with the kids without my husband ( he has to fly because of work). Our usual vacation is to Florida for Disney but next summer we are wanting to do something different. I will be spending 4 to days driving with 3 kids ages 12, 14 and 15. I'm looking for advise on places to stop and things to see. This will be 1 of the last road trips we all go on together and I want it to be memorable and some what stress free.
