Kari, if he comes through on going to Gatlinburg and you want to see something unusual then take the Gatlinburg Parkway between Gatlinburg and Pigeon Forge one afternoon and turn left beside the Gatlinburg Welcome Center onto Banner Drive. Bear left onto Wiley Oakley Drive and follow it up the mountain.
A female bear sow with 5 cubs (an unusually high number of cubs in one litter) has been foraging for food in the vicinity of 1009 Wiley Oakley Drive for the last month. If you see them, stay in the car and don't get too close.
I have pictures of her with 4 of the 5 cubs taken from the back porch. The 5th cub was camera shy and ran away when he saw my niece taking pictures of his momma and siblings
Also, all of the roads through the National Park with the exception of U.S. 441 between Gatlinburg and Cherokee, N.C. are closed but U.S. 441 has some pulloffs with great vistas, especially around Newfound Gap. I heard that the road to Clingman's Dome just south of Newfound Gap is still open but I haven't personally verified that to be factual.
The elk are in rut up until the end of the month or the first week or two of November and if you go to Cherokee there are a couple of open fields near the Ocanaluftee Visitor Center on U.S. 441 where you can see them early in the morning and also between 3 and 7 P.M. I haven't been down there yet this year because I plan to combine 2 trips into 1 and go into the Cataloochee Valley at the same time to photograph them there but the valley is in the National Park and the road is closed. The valley has the largest herd but there is a modest sized herd near near the Ocanaluftee Visitor Center.
If you go and hear the sound of a trumpet don't worry it ain't Jesus, it's a mature bull elk warning all the young bulls to back off.
