I spent a lot of time at this park when I was younger, particularly participating in practices/games for a variety of AYSO teams. Back then and even as late as last year myself and the locals would always refer to it as Hull or Hull Street, the name of the street it's on. In May 2014 it was renamed after George S. Lima Sr., a large contributor to the city of East Providence.
The cache itself is hidden in pretty familiar fashion, the biggest difficulty may be the muggles in the park. Good luck, and as always, happy caching!
