For me, one of the most appealing aspects of of OGR's forum is its atmosphere and its culture, which is summed up by a sig line of a long gone OGR member (that, sadly, I can't recall the name of): "It's a great big tent with room for everyone!".
By that I mean there's 3R traditional, 3R Hi-rail, Tinplate, Marx, S, HO, G, N, Z, all persuasions of model railroading, plus there's also "specialty" forums. Further, here at OGR there's really no "wrong" way of enjoying your trains. Seems the vast majority of us here get it: There's a huge spectrum of "fun" to be found in the hobby and however a person finds "fun" is the "correct" way for them to enjoy their hobby of model trains and/or hobby of railroading in general.
So, even though my involvement here may ebb and flow... I always check OGR's forums, sometimes several times a day.
After all, OGR illustrates well that model railroading is "a great big tent with room for everyone"!
