I get it. But it's a shame nevertheless. I've participated in other hobbies such as high powered rocketry and airplanes, both flying and static and it always seems to come down to models of the same 'ol rockets and the same 'ol airplanes. There seems to be a lack of imagination and sense of history. But then, its all about business and what sells, isn't it? The Chrysler Corporation found that out when they tried to step ahead with the Airflows. They stayed with the idea for three years until they finally got the message: the general public almost always goes with the common denominator or with what is familiar. However, that said, if Burlington and UP hadn't stepped up with the Zephyr and the M-10000 streamliners, passenger rail service would have died back in the Great Depression years. Hooray for them! They had the guts and the imagination. So, I'll sit here and hope to find the Green Diamond on eBay or a used-train company. It won't go cheaply and that's the irony of it all. There's a market out there for "the different." But, are there companies out there willing to take a chance with imagination?
