Acting while travelling in old American west (2,5)
I believe the answer is:
on stage
'acting' is the definition.
(I've seen this before)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for on stage that I've seen before include "in front of a audience" , "Acting" , "like passengers in Wild West" , "Treading the boards" , "performance" .)
