Google has added the Grand Rapids area to their Street View feature on Google Maps. Judging from the pictures, it looks to be from around September of last year. Coverage mostly focuses on the area north of M-6, south and west of I-96, and east of Wilson / I-196.
I remember seeing one of the Street View cars near Byron Center & 52nd, but that area isn’t currently available for some reason.
If you find any interesting shots, post them here. The pictures are all from daylight hours, so Division / 28th should be (relatively) clean. Google is supposedly blurring the faces of people in Maps now, but I haven’t noticed anyone blurred out yet.
