Bucket Brigade, Missoula, Montana

A lone yellow bucket, beaming away amidst the mixed blues and rust.

Is there a story here, I wonder? (Or the beginnings of a children's book... hmmm....)
Was this arrangement on someone's bucket list? (Hahahahahaha! couldn't resist!)
Did it get placed just so to satisfy someone's artistic bent that usually has no outlet in a busy day in the yard?
Or was it just pure chance, mixed with happenstance of my angle of view on a random lunchtime walk?
I have questions. Almost always. Sometimes deeper than these. Or not.
