Those sound like the MCI D4500CT's being used, Calvin. I believe the bus operators use those same buses on Saturdays, unless a different operator. I believe about 22 of those buses are numbered 22XXs.
I still take photos of buses and subways in my spare time. I don't do it too frequently though. Sometimes the bus/train operator do have issues with passengers/transit buffs taking their photo, so I have to respect their wishes.
