We're blessed to have so many of our country's most beautiful and special places preserved as national parks, monuments, etc. Sorry to hear about The Great Smoky Mountains' recent changes. I spent many days backpacking there a few decades ago. So beautiful.
A bit of interesting history about The Great Smokys...back in the 1920s it was challenging Shenandoah's lead to become the first/only National Park in the eastern mountains. Unlike many western parks that were created from federal lands, Shenandoah's proponents were having to raise funds to purchase private lands...contributions from everyone from school kids to businesses, as well as state government contributions. The Smoky's were raising funds, too...but then John D Rockefeller made a multi-million dollar contribution and they got to the goal first. Fortunately, both parks were established.
A big difference was that the deal North Carolina insisted on with the federal govt was that there would never be a fee to enter their park, it would be free for all...still is. Whereas, Shenandoah charges $30 for an entrance pass, or $55 for an annual pass. For us seniors, the lifetime "America the Beautiful Senior Pass" is a one-time $80 purchase, good for all national parks about 2,000 other fed lands.
Now the National Park Service is underfunded, so looking for ways to increase revenue. The Smokys decided that the deal NC originally established would have to be honored, so no entrance fee...but came up with the idea that it didn't apply to parking fees...so that's their new "creative" revenue source. Sort of a "come in free, but don't stop, or you pay." The GSNP is the most visited NP in the USA.
Shenandoah NP has no parking fees, but a steep entrance fee, especially for a young working family wanting to take their kids to the outdoors. Just this week, SNP instituted a new fee...limited to backpackers...used to be free to backcountry camp, now a $15 pass must be bought online for your trip...applies to AT thru-hikers, too.
This is in addition to the hundreds of volunteers who maintain trails, purchase adjoining lands to preserve, etc through various hiking clubs and non-profits such as the Shenandoah National Park Association, and the Shenandoah National Park Trust.
