We use three field L and T dwarfs which were discovered to be wide companions to known stars by the Two Micron All-Sky Survey (2MASS) to derive a preliminary brown dwarf companion frequency. Observed L and T dwarfs indicate that brown dwarfs are not unusually rare as wide (Delta >1000 A. U. ) systems to F-M0 main-sequence stars (M>0. 5Mₛun, MV~ 10 times as frequent for wide than close separations. A brown dwarf wide-companion frequency as low as the 0. 5% seen in the brown dwarf desert is ruled out by currently-available observations.
