I've taken the I-10 from New Orleans to California and back twice. I've also driven to the Colorado Rockies twice. I love road trips, I love the American West (and Widespread Panic).
Anyway, I've been watching this stuff on HD TV about Yellowstone(r) and Yosemite and I get all goose bumpy. I'm sick of being in this topographically boring region. I love mountains.
I wonder what people say is the most beautiful part of the Americas. Go ahead with South and Central if you must.
