TriMet Ride-A-Long | Line 30 Estacada, Ride Along

the most senneic TriMet route in the system. It's probably the most unique route (if we aren't counting discontinued lines because that would be Line 30E)
Bus 3919
2018 Gillig BRT
Cummins L9
Voith D864.6
I'm planning to do more of these in the future.
