Not all great art is on display in a museum or a gallery. Some of the most fun art to discover is street art painted on walls, fences and garage doors. In New York city, the best examples can be found in the Bushwick neighborhood of Brooklyn, which has become a fertile ground for artists that prefer to use a spray can on a wall in place of a paint brush on a canvas. Wander the blocks around the intersection of Troutman St. and St. Nicholas Ave. and explore the mural art that makes up the Bushwick Collective. You’ll find that these days, more than just a tree is growing in Brooklyn.
