Troutman, I was being fairly serious about their naming a stream after your son. You, of course, would need to agree to such. Shoot, I heard that back when the park was being surveyed by TVA/USGS, someone on the crew would ask, "what are we going to call this one?" To which someone would reply, "lets name it for our rodman. Let's go with Toms (or whatever) Creek?" In my opinion, a 12-13 year old angler catching a speck where none were once thought to exist is about as good as it gets when it comes to surveying... and that's coming from someone who was a rodman working summers with TDOT. Hey, I busted my buns toting that rod and bushwhaking and I never got as much as a culvert named in my honor.
The Department of the Interior would probably cite a bunch of reasons why there can be no Evans Branch, but the thought they might just go along is intriguing. After all, we're not talking about the Nobel Peace Prize here.
