It turns out that Gene Roddenberry was a model railroader!

I've been a fan of Star Trek (in all its incarnations, but specially the Original Series), since the late 60's. The first episode I saw as a child, Charlie X, freaked me out so badly that I couldn't watch the series the rest of the season. I stared watching again the following year.

Can you imagine the layout you could build on the holodeck?!!

Anyway, it looks like Gene had a pretty nice layout there! Live long and prosper!
