Sometimes these “then and now” columns get frustrating. When I discover a great old photograph of an unknown building, I check out the location on old maps and in aerial photos, then search the address on current sites such as Google Maps and too often find an empty lot or an ugly pole building. Sigh. So for my mental health I’m going to focus the next few weeks on existing buildings with happy endings or great potential, such as the neglected but wonderful Ritz Theatre.
