Our guide was incredibly informative, down to earth, and punctuated my short trip to Chicago with some great knowledge about the art and communities in Chicago. He kept us engaged by asking us questions of the graffiti culture we're from and by supplying excellent tidbits about the use of color, design, and backgrounds of the artists mentioned along the trip. If anyone's looking for a guerrilla-style look into the street art of Chicago, this tour is the way to go!
