Although they've already disclosed the 2004 test of the "Wind Wagon" what was your favorite Road & Track "April Fools" road test? For me, it's a toss up between the time they actually tested a "road" (Route 66) and the Goodyear Blimp (weight as tested . . -0 lb. ). But I do have a soft spot for the pogo stick and the Sopwith Camel.
