I agree with everything you said. Is 28th Street (in Wyoming) even still a "shopping and dining destination" for all of West Michigan? I don't really see it as such anymore...it's more of a dying area. Has anyone else been in Rogers Plaza lately? I have, and I got out as soon as possible because I felt so depressed in there.
Wyoming does not have a downtown, and it never really has. Grandville is really the only inner-suburb that has any semblance of a downtown. Any development like this that takes place off of 28th Street will, in my opinion, fail. If they continue to treat 28th St as simply a way to get from one point to the other, I'm afraid that all Wyoming will end up with is a failed 'town center.' The problem with places like Wyoming, Kentwood and Jenison is that they are not built around actually villages or towns (or at least what once were village centers are no more). These places (minus Jenison) incorporated purely as suburbs of Grand Rapids. If Wyoming officials actually want some sort of downtown, I think it will have to be directly on 28th St. This would be difficult to work-out since 28th St is a state highway, but I'm sure compromises could be made to calm the street down in order to provide a pedestrian-friendly environment.

Your last two paragraphs couldn't be more true! I'm still living in Byron Center right now (just graduated), and you wouldn't believe the amount of families that are moving out of Wyoming to Byron Center...has it really been that long ago since Wyoming was the place to be?
