Own your own Speedster radar gun
Operate your own speed trap and shake down drivers for bribes.* Or just clock how fast your friends are heading for the lodge when the beer is flowing.
*Accepting bribes may not be legal in your present location. Owning handcuffs and having a gf who calls you "officer" does not actually make you a policeman, so don't get busted impersonating one. ;) ;)
