Vaguely Helpful “How To Play” - 1800 Colorado. An 18XX mini.

About 1800: Colorado, from BoardGameGeek:

A mini 18xx game, set in Colorado, and appearing in issue #17 of Rail Gamer Magazine. It's for either two or three players, and there are only nine playable hexes, so it's extremely "mini". The two player game has 2 corporations, and the 3 player game has 3. There is an interesting bond mechanism that allows directors more control over how much money gets into the company.
