So today I left the office about 7 minutes early. Got downtown just in time to get my connection.
Today was a record. I was home by 5:20PM. Not bad RIPTA. Of course now I know the trick.
If you do get in early you head north from the stop, not south into the plaza. Because then you can catch the connecting bus on Exchange Terrace.
Pretty much all the buses headed through the city go over Exchange Terrace.
