Crazy place for a flag? (2,3,4)
I believe the answer is:
up the pole
'crazy' 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 up the pole that I've seen before include "Slightly mad - on the wrong track" , "Unstable" , "Wacky" , "Maybe trying to repair telephone line" , "as climbers could well be" .)
