I've subscribed to Model Railroader for decades and receive the monthly NMRA magazine - don't recall ever seeing most of these layouts in either place, which surprises me. Perhaps that's due to the focus on HO and N in those publications.
Seems like an opportunity for OGR - @Allan Miller and @OGR CEO-PUBLISHER, I hope you plan to contact some of these folks regarding articles and/or producing a video. I know that OGR normally relies on reader submissions, but several of these layouts might be worth some special effort to pursue. (If I knew any of these layout owners personally, I'd try to do it, but I don't.)
