Aren't those monsters coming out of Richmond Mill CNBG? Richmond Mill is at 34.872 latitude, and I'm at 35.615; is that a significant difference?
Good Lord, man, that's 0.743!

Seriously, Walt, Coppernose should do great for you in middle Tennessee. I wish my ponds were 2 states farther South, so I could stock them (although that would make it hard to walk to them after work on weeknights).
The closest I can remember anyone having problems with CNBG due to Latitude was no nearer than the middle of KY.
