Thompson Grove Park (Manalapan, Monmouth County, New Jersey) just opened a few days before we visited today. Though it was a nice park, we had a rather awful experience. It was FULL of horseflies. And the off did not even help. It was rough.
Overall thoughts of the park were that it is very nice. They did a great job cleaning up the rubbish that was once found on the property. We were told by some locals that this place was completely full of garbage and old cars before they started the project. What we have now is a GREAT place to visit and enjoy.
