Roadtrip

Starting this Saturday, I'll be mainly offline going on a roadtrip as it is a typical activity in the US. We'll go to different National Parks and end up in San Francisco. I never understood, why people do so many road trips, but as I booked my flight back from SF to Santa Barbara, it turned out that this flight will be as expensive as the car we rent for five days! Thinking of trains, it takes nine hours or more to get from SF to Santa Barbara. And it's kind of impossible to reach the National Parks with trains or buses if you're not considering traveling with an agency.
