Here is a picture of the state license plate game and some caramel corn I made for my kid's trip to San Diego. Please notice the very cute label!
The post at The Dating Divas has other great ideas to pass the time in the car that would work very well for kids. I am going to include my grandma's recipe for caramel corn here because it is to die for! My grandma used make it in Colorado and chipmunks used to climb her window screens to get it!
1 cup brown sugar
1 stick margarine
1/4 cup light corn syrup
1/4 tsp. butter flavoring
1/2 tsp. baking soda
Cook above for 2 minutes and pour over 6 quarts of popcorn in a paper grocery bag. I usually add some caramel and then shake the bag before adding more. Microwave for 1 1/2 minutes. Shake bag. Microwave for 1 minute. Shake bag. Repeat one more time. I let my caramel corn cool on a baking sheet before putting it in a container. Enjoy!
