Kind of a weird topic but, you ladies seem to have such cool ideas on other things so, how can I keep my 6 and 8 year olds occupied for a 10 hour drive?
​I've made a scavenger hunt and of course we will be bringing electronics, art supplies and etc but those usually only last a couple of hours before the "I'm booorrreeddd!!" whimpers.
