My first foray in making a POI.
I gathered the information from here http://parks.westchestergov.com/parks-and-recreational-areas and just went to Google maps to get the coordinates. I've also added phone numbers, and hours of operation.
It loaded with no problem whatsoever on my Garmin Nuvi 3597. For what it's worth, I also used Extra POI Editor v5.91
