Vandals or drunks last night busted off one of the park bench rails and threw it 10 feet. The bolts are still attached to the cast-iron frame so all that's needed is a new wood rail.
Bit by bit Wooster Square Park is losing its benches, beautiful iron fence, and losing its trees, but in the process gaining lots of trash, tiny liquor bottles, fast food wrappers, pizza boxes, foil cigar wrappers, empty cigarette boxes, beer cans, etc., even though every exit has a garbage container and a few more plastic ones have been set here and there inside the park.
Can we exercise some control over this lovely resource and protect it a bit better than we have been?
Everybody should be free to use the park; nobody should be free to abuse it.
Answers, anybody?
