The last time I was in Yellowstone National Park was 15 years ago. On that trip, I had detailed lists of everything I wanted to see and do and what time of day to go to each location for the best lighting. By contrast, on this trip I have only a vague idea of which direction I want to head each day and am leaving the rest up to whatever I feel like doing at the time. Spontaneity isn’t usually my style, but I’m learning to embrace it!
