A statue of a horse and rider!

Probably of a general riding his faithful steed...
rearing in anticipation of the coming battle...
saluting his comrades in arms...

(or waiting for pigeons to start dropping their little missiles on him!)

But it's just Grandma...
riding her buddy, Pal, across the hillside

when she noticed
the sun making their shadow
into a simulated statue in the park.

Grandma isn't saluting...
just aiming her cellphone camera!

But it was fun to ponder on this story!
