At their Open Houses, the Crescent City Model Railroad Club conducts a Scavenger Hunt to see how many anomalies their visitors can find. For instance, they have a five legged horse and a two headed cow.
Since they run a relatively prototypical railroad (meaning the rules of the “real” train universe apply to their miniature version), they try to logically explain the existence of everything on the layout: it’s called credible plausibility.
In the vicinity of the above mentioned mutants is a Toxic Waste Dump. What better way to account for putting a new twist in DNA. The club layout also has two Bigfoots (but we all know that they’re real and don’t really need an explanation.)
The CCMRC will have 5 open house days in November 2016 through January 2017. More information may be found on their web site: http://www.ccmrc.com/
