Perhaps many of you already are aware of this site. I discovered it while reading about the secret 30 acre proposed development downtown. That thread has ended, but there are others of equal importance, like what is the best Hot Dog in GR. My vote goes to Grand Coney, but it looks like the overall winner is Yesterdog. Seriously though there are other subjects for discussion on this site all devoted to the city of Grand Rapids. You have to be a member to contribute to the discussions, but it is fascinating to see what people are saying about things that are relevant to the community.
