It seems that every night behind PS 217 and up until Manhattan Park playground someone is eating dinner and drinking and not cleaning up after themselves. There are empty takeout containers, utencils, juice bottles, and general junk around and under the benches on the river. Can someone please start the daily patrol of the island to clen these things up? If public safety sees people in the evenings eating/drinking maybe they can give them a friendly reminder to throw everything away. Thanks.
