Best way to go cross country you think?

I think it would be wonderful to go cross country on a bike and by bus for areas a vehicle would be needed. It’s a refreshing perspective to see things like a local and feel the vibe authentically, like the DNA of a place becomes internalized. It is also a sign of respect and love to the planet and cultures to create a positive carbon footprint until hydrogen and crystal renewable energy can be stabilized and standardized that is! : ) I would love to travel to all the pyramids of the world, especially Egypt biking & busing the tight spots smelling the air and feeling and intimately knowing the vibe of the evolution of a place & its peoples.
