The new "Business US 12 (Baraboo)" will incorporate the old West Baraboo business route, and an extension to the freeway means that BOTH endpoints will be different from where "US12_W" and "US12_E" are in the current Baraboo file. Should I find slightly alternate names for the new endpoints such that US12_W and US12_E remain in their current locations but as hidden points, or break it entirely and tell everyone who has entered either the Baraboo or West Baraboo routes that they'll have to enter the new names?
