Well, the bluebonnets give this one away - definitely a Texan landscape - and as always, Milbie has painted a scene that I would love to visit!
This is a plein air painting, and part of a gorgeous trio of paintings that go together perfectly.
Part 3 of Milbie's trio of little 9x12 paintings, this image would be the right hand side painting - the 2nd one is "Hidden Creek".
