I prefer this show to Cities of the Underworld, which Don Wildman also appeared in. This has more variety, doing multiple locations per city or area. That makes it a sort of sampler, where you may discover something you did not know would interest you, and a good selection for a multiple viewer household. Ruins are shown with their history in detail, with names and dates, so this is more than just an "oh, wow" tour and things currently in use are also put in their historical context. Shows include the long-distance water supply to Los Angeles, the floating bridges of Seattle, grain storage in Buffalo, and the Pillsbury flour mill in Minneapolis. Don Wildman does his presenting in a calm, low-key sort of way, so you can watch several shows straight through without getting worn out. This Travel Channel series is not a hi-tech equipment display series, and does not have the odd background sound effects which are a characteristic affliction of History Channel programs.
