My most memorable and best travel experience in 2017 was Yellowstone National Park. Wading in hot springs (Boiling River is the best!), eagerly waiting for Old Faithful to erupt, watching the 'crazy' bull elk during their rut in Mammoth Springs (love the bugling!), crossing paths with a coyote on a hike, and being immersed in such a colorfully rich, steaming hot, active volcanic, boiling mud landscape made this trip so exciting and awe inspiring. A natural wonder that enlivens the senses and is a must see!
