On what seems like a thirtieth re-reading of the original Avalon Hill rules, it struck me that off-board locations are not considered "cities". There are small (AKA dits), 2 small (AKA double-dits), large (normal cities), and 2 large (double-O) cities. Additionally, the rules state:
Avalon Hill rules wrote:
A route may begin or end at any city. The
”arrows” at which track enters the red hexagons may also form the start or finish of a route (or both if
different red hexagons are involved) but these red sections may not form part of the middle of a route (i.e.,
they cannot be run through).
This seems to preclude red off-board locations as being considered cities, leading to my rules question:
Can a corporation run a legal route between a city with the corporation's station marker and an off-board location with no other cities between?
I know that the standard answer is that you can run between two "revenue centers", but this isn't mentioned in the original rules or Steve Thomas's clarifications, and I'm wondering how this came to be the consensus.
