The Smokies used to be my bete-noire, because 1)I want to section hike the entire AT (primarily), and that big dumb chunk between Fontana & Davenport Gap wasn't going anywhere. It does nothing for my OCD to not have continuous sections done, but I digress, 2) because I hate sleeping in shelters with a passion, and 3) rules and permits and yakety yak.
My mind has been changed however. I've seen some things that have convinced me it's not all that bad. Heck, I have to pay $15 to camp at my nearest state park, and it isn't all that great. But places like that have to be maintained. I will say that the AT through the Smokies was pretty damn well maintained, and I appreciate that. It's a national park for heaven's sake (and a pretty ecologically diverse one too). I don't have a problem supporting that.
So my previous stance on the Smokies has changed. If a person really hates rules like that, there are another 2,000 miles of the AT outside National Parks that they're free to roam. There are dozens of trails in the Smokies, and maybe one day I'll go explore some of them, but that's not high on my priority list.
