I really like long drives (no heavy traffic please!) you can see the terrain change as well as know a lot about the area just by observing the things you see while on the road.

As we left Yosemite, the landscape changed from the lush green and majestic redwood tress, to the dry and still interesting desert of Las Vegas.

Here are some photos I took from the bus - have a look.

Remnants of the trees burned by the forest fires of a few years back
