I've ridden some of HogWild's roadbook routes, and he does an extremely good job of making it a realistic Rally simulation, meaning it's more than a dualsport ride. It's more of a puzzle, or a game. GPS tracks wouldn't be the same at all.
I really appreciate the work the Scott does- it helps to train pretty much all American rally riders and hopefuls.
He pointed out Crawdads' DS route if that's what you are looking for; rally navigation is an entirely different thing.
