One of the most puzzling behaviors exhibited by cool brown dwarfs (BDs) is their rapid evolution from very red (J-K~2) to very blue (J-K~0) near infrared colors at the boundary between L and T spectral types, marking the transition from cloudy to cloud-free atmospheres. It has been suggested that this rapid evolution is caused by the sudden fragmentation of cloud decks above the photosphere. We are conducting a monitoring program of ~ 50 late-type BDs for rotationally modulated variability in order to test this hypothesis. However, due to the rapidity of the L/T transition, it has been suggested that the majority of so-called transition BDs are actually the spurious result of unresolved binarity. This hidden binarity greatly complicates the interpretation of variability studies. Therefore, we are proposing to observe a subsample of early T-dwarf targets with intermediate NIR colors (0.3
