An amusement park might seem an odd place to put a Morrow Project base, but it has several assets
1. Good accessibility (easy access to Interstate road system) but not an obvious place for refugees to try and reach
2. Easy to get personnel there before freezing
3. It's a good 'front' when recruiting craftsmen, technicians, engineers etc
4. 'Dollywood' has several displays which would be useful in the Reconstruction Effort (including a working grist mill and a functional steam train)
It could also be used as a Psych Test facility (Did the prospective MP member run away from the Southern Gospel Museum and Hall of Fame? How Fast? Was he/she screaming?)
