There is another bumper on the side of fifth Ave, between Robinson St and the entrance to the Blvd/Parkway. Right next to the "cattle chute"
It looks as though it was violently separated fom the on which it formerly resided.
Unfortunately, when I've gone by there in the mornings, I have not had time to pick it up and securely fasten it to the front of my bike.
It could be a movement!
