Not to challenge the veracity of your info....but has anyone seen anything official? The GSMNP website doesn't have anything regarding the closure. Specifically....they need to answer these questions:
Can I pull over at a parking area....get out and walk down to the stream and fish?
Can I daypack into a streamshed to fish?
Can I hike on a backcountry trail?
Common sense says these activities would not require the services of the Park Service....but we are dealing with the federales. I digress.
