Another thought: How well would creeping vines do in Mont's climate? I'm talking the kinds that enjoy growing all over the sides of buildings. I can see some decids in there without their leaves, one pine tree (like I said, they're happy in winter and look good with the building), and my eyes can't easily make out what's going on in the space between the street and the building proper. Is that the winter mix of Grass-sidewalk-dirty snow?
