George Washington and Dwight David Eisenhower.
Compared to this bunch of weasels (OK except Duncan, whio can't draw flies) no friggin' contest. OK., OK, maybe Thompson ain't such a bad guy. Wake him up and we'll talk.
Washington, yes; Eisenhower, maybe. The Interstate Highway System was Ike's baby and it has surely changed America, although whether for good or ill remains to be seen. The mall-ization of America depended on it and that has had some pretty serious effects on the economic viability of small-town America.
