Strange as Gideon in coastal location (3,5)
I believe the answer is:
san diego
'coastal location' is the definition.
'San Diego' can be an answer for 'location' (San Diego is an example). I'm unsure of the 'coastal' bit.
'strange as gideon' is the wordplay.
'strange' is an anagram indicator.
'as'+'gideon'='asgideon'
'asgideon' is an anagram of 'SAN DIEGO'.
'in' acts as a link.
Can you help me to learn more?
(Other definitions for san diego that I've seen before include "Pacific port" , "Californian port" , "US city" , "Calif. naval base" , "Southern California naval base" .)
