Roadrunner Twice

The *plan* is for it to be a "settling the frontier" book, only without Indians (because I really hate both the older Indians-as-savages viewpoint that was common in that sort of book, *and* the modern Indians-as-gentle-ecologists viewpoint that seems to be so popular lately, and this seems the best way of eliminating the problem, plus it'll let me play with all sorts of cool megafauna). I'm not looking for wildly divergent history, because if it goes too far afield I won't get the right feel.

I'm currently assuming there will be African slaves, possibly even more (since there won't be any Native Americans to have already done a certain amount of prepping land for human occupation, nor to be exploited later).
