This isn't a huge deal considering this is going to describe a drop-off stop, but the BxM3/BxM4 on Bustime (which means on the newfangled screens on the Prevosts also) show the dropoff stop at 5th and 87th, but the drop off sign is at 5th/84th and that's where the drivers all stop at because the stop's been at 5th/84th for years...
I usually take the buses to Midtown so this doesn't affect me, but for the sake of conversation what's the *official* stop in that area?
