Last weekend we attended the 8th annual Santa Fe Model Train Show. It was cheap entertainment and we ended up having a good time.
Of course there were lots of families there, but there was also a good cross section of the community there as well.
These folks take their trains very seriously and have quite a bit of money wrapped up in their hobby. I was most impressed by the amount of effort they put into the miniature scenes, complete with realistic buildings and landscaping.
