Airline travel is so common these days, it's like taking the bus. It may be hard to believe, but there was a time when people used to travel across country on the DOG (aka the Greyhound bus).
Here's my story about the DOG.
Roman Holiday boarded the DOG in upstate NY with my climbing gear and a jar of peanut butter, headed West via Rt. 80. About 3.5 days later, I was sleeping next to a river in Yosemite Valley with a nearly empty jar that same peanut butter.
Was it worth the 3.5 days sitting on my butt?
Heck yeah, I saw the land scape of the USA. I ate at truck stops. I met funky people along the way. I took showers in restroom sinks.
It was my own personal "Travels with Charlie".
