Some decorations on a chain link fence around a vacant lot next to the OMSI MAX stop. I don't know anything about who created it, and I'm sure it's only meant to be temporary until the lot gets developed. PortlandMaps says the museum owns it. Come to think of it, I vaguely recall that they either bought the lot or had it donated back when I worked there, about 20 years ago. So I wouldn't exactly hold my breath waiting for a futuristic new museum expansion anytime soon.
