I walk almost daily for a mile or so directly on top of one of the world's most important refined-oil products piplines.

The national park and trail are only there because of the pipeline. I see hawks, deer, and beaver all the time, and there was even a huge alligator once, at almost 34 degrees north! A special and natural spot now surrounded by suburban hustle and bustle. I suspect a natural gas line crossing the AT will be a huge nothing burger for future hikers.
