Wild adventures indeed. I don't know if the fellow on the left is an ally of the Blackfeet tribe, or some French guy Frank sent ahead to make sure no one shot at the Steam Horse.
Why bother shooting at it? You know that thing was so damned fininicky it broke if you just looked at its hinky. Honest to God, what was he thinking? Sure, regular horses had their quirks, but at least you never had one explode on you.
