Somewhere dangerous or safe (6-2-3-4)
I believe the answer is:
middle-of-the-road
'safe' is the definition.
(I've seen this before)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for middle-of-the-road that I've seen before include "Safe" , "Average" , "place for dangerous drivers?" , "Unexciting" , "Avoiding extremes; moderate" .)
