Seeing wildlife is an up close and personal thing at the Global Wildlife Center near Folsom, LA, north of New Orleans. The animals come up to the wagon train to eat from the visitors' food cups.
I love these lovely crystalline structures that grow in the pools of geysers at Yellowstone National Park in Wyoming. Unless I am mistaken, that is a quarter that someone dropped (hopefully accidentally) on the "flower" -- it gives a sense of the dimension.
