I was looking at some old IFR Refreshers tonight, and found the IFR Quiz
from September 2002. See http://204.108.4.16/d-tpp/0503/00282I2C.PDF.

Question #4 asks how to identify TANDS, and the answer they give is "BNA
DME and Livingston's R-270". Isn't that kind of nuts? The DME arc is
almost tangent to the LVT R-270, and would thus give an extremely sloppy
fix. The only rational ways in my mind to identify TANDS would be to cross
the BNA R-106 with the LVT R-270, or the BNA R-106, DNA 24.7 DME.

Is there something I'm missing here?
