I was searching for some ideas for our upcoming almost cross-country trip and I found the most fantastic website:
It's full of fun games for all ages of kiddos (even babies and toddlers), snack ideas, and general travel trips.
Even though I've taken many road trips with my kids, I still saw some ideas that made me go "DUH! Why didn't I think of that?" (like covering the seats with old sheets so it's easier to clean up crumbs and packing homemade snacks in ziplock bags instead of dumping money at the gas station for snacks)
So happy clicking!
