12 friends and I flew from Hawaii to California then drove from California to Illinois in a van to go to a music festival. Then tuurned back around for California then flew back to Hawaii. One month on the road. I wanted to murder every single one of them in the face so hard by the time I got back.
1,000,000 isn't that bad of a goal. Just a few road trips from California to Alaska and back will do that. Amazing scenery on that trip too. I'd do it again at a moments notice, if fuel prices weren't so high, and my vehicle wasn't so innefficent.
