Yeah, In my high school years (06 -10) I use to go out of my way to fan B103 on fridays, I loved that nonstop portion, it was unique for an NYC local bus route to have such an long nonstop portion, unlike the Q53 under Triboro the 103 nonstop portion made sense as it ridership base was Flatbush & Canarsie residents trying to travel to Downtown BK.
I will say that B103 park slope stop under the train stop was clutch when I bought something out of the nearby Lowe's and didn't feel like taking the train home lol.
Those MCI classics were underrated, only transit bus I been on that can match the comfort of OTR coaches.
