I would think it all depends on your hiking experience. I once thought if I didn’t have water when I got to fresh water, I was doing something wrong. Now if there is water somewhere today along the trail, I know that I will get to it and I will have more than I need.
It makes a difference if you want coffee in the morning and oatmeal before you hike too. I have camped without water and ate breakfast later or skipped it and just ate a big lunch. It just all depends on what you want to do. After 700 miles you get used to whatever the mountains throw at you.
Camping in the smokies should be great. I went thru there so quick that it didn’t matter how far away water was. I also had no problems because we had snow melt. If it rains, you’ll have oottles of water and if you filter, you may even be able to dig open a dry spring that isn’t even on the maps.
It just depends on what you are willing to tollerate. Most thruhikers will drink right from clean water sources, and boil pond scum if they think they need water. Have fun no matter what. Wish I could be there in August. It should be cool nights and terribly hot days.
