Circulator is owned and operated by DDOT (DC Government) and MetroBus/Metro is operated by WMATA (conglomerate of stakeholders including VA, MD and DC), so we can do it only by working together.
BTW, WMATA is launching NextBus which is ETA for MetroBuses in early July. So we will see what it is and how it works, and will try to integrate, to get the complete picture for bus transit in DC.
