They have this program call Modern Marvels on the history channel. They touch on a variety of technlogical advances. Well last night they had the history of 4x4. From the early 1900 when FDM (?) and Willys were competing for the military's first motor vehicle contract, to replace horses to present day 4WD and AWD. It was really interesting and I am sure everyone on this board would get a kick out of watching it. Check your local listings.
