Have you noticed the Heritage Walk signs that have been popping up on downtown lamp posts? On the sidewalk side of the posts are pictures of historic buildings with instructions for calling in to a cellphone-based tour for more information. But in most cases, the picture of the old historic building is all there is to see. Site after site has been demolished to make way for new development. There’s almost nothing left of the town I grew up in. Our heritage is that we have none.
