I like to watch the sunrise and the sunset in the park...I like to photograph wildlife too...sometimes (while backpacking) I will hike to a spot that I feel will be good to view and photograph the sunset or sunrise.
Often I'll get to these locations with a good amount of time before the sunrises so that I don't miss anything or the early wildlife. Sometimes I'll even go so far as to conceal myself from the wildlife in a blind (a tent works great) and I'll wait for the light to be just right to get the chance wildlife shot with my camera... sometimes....I fall asleep while waiting....but I'm not camping! I'm waiting.
I often hike to get away from civilization and people so I tend to avoid them while in the GSMNP and other places..Rangers included.
A stealthy photographer often wiitnesses things that others don't get to see. The GSMNP has a wonderful system of shelters and backcountry campsites and strict rules for camping overnight inside the park...kind of like the AMC further north...where I like to take pictures too.
