May is not the time to visit Yellowstone, only because most of the park is still shut down. There was still a lot of snow, and some roads were still closed. Aside from that, May is good for seeing tons of wildlife, which was a cool trade off. I personally preferred the areas with the mud pots and hot springs because they are so other worldly. I seem to like things that are completely out of the norm for me to see. It's strange to become familiarized with the sulphur smell that lingers in the park, but it would be weird to not smell it while visiting. It was also interesting to see how the climate and season effects the water flow in these springs which change the entire look of the environment. The more water shed the more microbes which give the springs color, but take the water away and it looks more like dried up chalk. There were parts that looked like what I would imagine the moon to look like because of the destitute dried craters that were left.
