Character 4:
In reply to Character 1 (msg # 4):
Perhaps hang and his master came to open up a store after successfully having one in another town.... Unfortunately his master died before they could set it up so he sold the stock, the cart and horse they had to pay for the funeral and he's staying in one of the boarding houses until he settles his masters affairs before heading back east
Unfortunately, this Sutter's Flats town is barely enough to call a town and there isn't even a boarding house in town, you would be having to find a place in the livery or some other kindness of folks to get a roof over your head. Or, could be staying outside too if preferred. :)
Perhaps you and your master were trying to do that in a town further west, one of the other railroad or border towns? You've come back east after running into some of that "anti-chinese" prejudice which ended up practically stealing everything your master left (maybe except for a couple of personal items of his you kept).
What would put you in a situation where you'd agree to a cattle drive and all the things that go with it?
