    "I have lived in this area most of my life 30 years. But it has gone down hill. The schools were some of the best now not to good. MS 13 killings every other day. Our local news is very controlling on what news we hear. My taxes on my home in manor park are over $13,000...for what potholes every 2 feet and drug/ gang problems. If you know my area you would know its the better place to live in this area....it only gets worse. Everyone is leaving Long Island"
