Well, get a great big wind tunnel? :^)

Look at the inverted spoilers on the backs of SUVs and old station wagons.





that's funny because i'm right in the middle of putting ladder racks on my
pick up truck cap. i have an piece of streamlined aluminum airplane strut
that i'm going to use for the horizontal. i was wondering if that might
kinda break the boundary layer. doubt it. hafta check with a wind tunnel,
which i have none.

Yarn, about 6 inches long, taped all over teh surface can show what the
