I myself love driving long distances, I have driven to Seattle from the Bay Area doing 55 mph and didn't even feel tired. My hardest drive is the first hour, as I am not quite into driving on a long trip, then I get an adrenaline rush and it's like Wow! I'm on vacation, after that I can drive 12 to 15 hours without any problem, However, if you have passengers, they may not feel like you do. I like to stop at malls to stretch my legs and get something to eat, not to mention break the monotony of the trip. This is what I do on long road trips. Have a Great Trip!
