"DENVER — A road into the piney woods can be fraught with consequences. That was the premise, more than a decade ago, behind a Clinton administration rule that restricted road building on millions of acres of national forests in the West. The so-called roadless rule, fought over in court from the start, was validated last year by a federal appeals panel, setting off a wave of euphoria among supporters and consternation among critics. But there is a big wrinkle here in Colorado, which was one of only two states — Idaho was the other — that at the urging of the Bush administration developed their own rules about roads in the wild."
