We feel the same way.
Roadtrips bring a family closer. We learn to talk to each other, be bored together, experience things together, play together, fight together, forgive together, move on, and be friends together.
You can't get that in an airplane in a couple hours with everyone plugged into their electronics and dealing with other people.
We recently went on a roadtrip to Whistler, BC. 4 days of driving each way..... 5000 km's roundtrip. It gives you the opportunity to learn to communicate with each other.
