There are a lot of cameras. All over Broadway, down these avenues where things actually are
This is why there's Riley on film a lot of places.
I have walked all over First Avenue, Riverfront Park, etc. I don't even know how to legitimately get to the river. Because walking near it, i have never, not ever come anywhere close enough to the river to have any danger of falling in it. If i had been falling down drunk, i would have fallen on the street, on the grass, on the sidewalk, onto a building or car or person. Because that's usually what happens.
Nashville is not some kind of port city. So, there's not dock activity that is common. There are barges that operate out of Nashville, i guess there are cameras around there.
