I think the S93 limited should run all day (at least on weekdays) as opposed to rush hours. That would take a load off the S53 and S62 to a certain extent.
I personally would like the S51 to have more frequent service during weekdays too.
Forgive me if this was discussed already, but how about an extension of the B36 from Sheepshead Bay to Kings Plaza via Avenue U. It would take a load off the B3 in my opinion.
I was thinking about how people in Mill Basin go about their transportation, not necessarily to connect with the subway at the Brighton line. I'll agree with you that there isn't so much ridership on the weekends on the B100
For now, I try to make signs as quickly as possible so if any custom colors or doubled lettered bullets will have to be rejected for now. I apologize for any inconvenience.
I'll try to come up with a double lettered bullet gallery sometime for me to use later on. I'll tell you when it's ready.
