A group in Boston has inscribed poetry on the streets of Boston MA; poetry that is only seen when it rains.
Using stencils and water repellent, the poems are placed on a sidewalk or similar surface. This “Raining Poetry” has been installed at multiple locations around the City of Boston.
The Mass Poetry group serves to draw people to poetry, and they are using this unique process as one way of attracting attention to it. As they say on their website:
Mass Poetry supports poets and poetry in Massachusetts. We help to broaden the audience of poetry readers, bring poetry to readers of all ages and transform people’s lives through inspiring verse.
