Cowboy may be seen here, avoiding saloon? (2,3,5)
I believe the answer is:
on the wagon
'here avoiding saloon?' is the definition.
I don't know anything about this answer so I can't tell whether this works.
'cowboy may be' is the wordplay.
I cannot really understand how this works, but
'be' could be 'go' (going is a kind of being) and 'go' is present in the answer.
This explanation may well be incorrect...
'seen' is the link.
(Other definitions for on the wagon that I've seen before include "Abstaining from alcohol" , "Teetotal" , "Off booze" , "Not drinking" , "Not taking alcohol" .)
