I started a new thread in the "In the Backcountry" area, but worth adding to this thread as well..
is up and running. It went online sometime between 6 AM and 9 AM EST
I made a reservation and got my order number. When I entered my order number on the page https://smokiespermits.nps.gov/gsmbctransactions.cfm
I received and error, "Your transaction information could not be found"
I called the backcountry office (865)436-1297
and Ranger James W emailed me the PDF Reservation form.
