9 Things to Do in New Jersey


  1. i lived nearly 60 years in the nutmeg state, and retired to monmouth county nj.
    expense wise and regulation wise, they are close. but, nj has a better social
    service system, while connecticut’s is abysmal at best. The garden state people
    are as warm as the weather, while nutmeggers can at times, be more
    stand-offish. my dad was from the bronx and mom is a a true new england yankee.
    imagine that, and here i am( and 2 brothers!).

  2. Forget these states, Florida, despite being drastically different from NJ, is surprisingly similar to it in many ways, especially in regards to its culture. Both states are known for their Latino/Hispanic communities of Caribbean descent, as well for their reputations of surfing meccas.
