Hooray for the trees! After spending the last few days in barren southern Idaho—which is virtually all desert—I was happy to see my tree friends again. Lodgepole Pine is present everywhere in the world’s first national park (1872). In addition, here is the world’s largest concentration of geysers (the most famous being Old Faithful) along with many falls, lakes, and wild animals. I encountered a lot of buffalo, including several who were roaming around on the roads (please drive carefully here).
