klang goes the Trolley, ring goes the Bell , I think is how the song goes..

Trolley is only for the tourists, summer and some weekends,
trestles are planked in and serve as the Riverwalk MUP where it's not dry land.

I ring my bell , they look around and move single file if needed..

I say "Hello", as I go by.

where the trolley passes the driver, invariably, waves.
