Where to fish this weekend?

Hey ya'll,

My wife and I are going to be at a wedding this weekend here:

197 Elk ridge
Butler, TN 37640

Any idea of some good spots to fish? I won't be able to get too crazy, as she'll have to be watching our 2 yo and 3mo, so I'd like a family friendly spot where I could still hunt some trout.

Also, where can I purchase a GSMNP permit for a day? Any idea how much they are?

Thanks.
