Most neighborhoods have an invisible boundary where public space ends and private property begins. Rachel Harms Mahlandt started questioning that boundary after discovering tiny installations scattered around Portland: a rubber duck exchange, a toy car swap, miniature galleries, and other invitations to stop and interact. She eventually built her own, then began mapping hundreds of similar projects through Sidewalk Joy. What started with a dinosaur diorama in her front yard has become a way for strangers to linger, trade something small, meet a neighbor, and treat the edge of private property as a place for connection.ADDITIONAL SHOW NOTESRachael Harms Mahlandt (LinkedIn)Sidewalk Joy (Site)Local Recommendations:‍Zuckercreme Strawberry MuseumMr. PlywoodThreshold BreweryTiffany Owens Reed (Instagram)Do you know someone who would make for a great Bottom-Up Revolution guest?
