Portage bhai, whazaaa.....My Brothaa.
I have to agree, the long trips can be tiring, specially with little kids, it takes toll on everyone. I have driven from Michigan to Virginia, several times. About 600 Miles or 1000 Kilometers. Very tiring trip. Alot depends on the car. The bigger the vehicle the better the ride.
On the Michigan-Virginia trip, I have driven, a Nissan Maxima, as well as my Ford Explorer SUV and my Toyota Landcruiser. The best ride was in Landcruiser. You don't feel tired in that big comfortable beast at all. The trip usually takes 7 to 8 hours, but in LandCruiser I felt like the whole trip was just 1/2 hour long, due to all the comfort and huge selection of DVDs, and CDs to entertain with.
The best approach is to buy tickets, specially when you are alone and also buy tickets from the internet on Cheaptickets.com, etc. You can fly from MI to VA with $100 fare. But by driving and eating out, you would easily spend $200 for the trip, for gasoline and food. But travel by car can be more economical than airplane if you are travelling in a large group.
