You need to contact a lawyer in the county where you owe the fine. There is probably a warant for your arrest. You could get pcked up here in MA and even held until they check and find out how minor it is. The problem is that they won't know that it is minor until after you are sitting in a cell for a while. Go on the internet, get a NJ lawyer and get it straightened out on your terms before you have to straighten it out on someone else's terms.
You should contact a lawyer that practices regularly in Hoboken, they are the ones who know NJ law and also know what the consequences are of your failing to appear. Technically, if you get arrested or stopped and it shows up on your record, they could hold you and transport you to NJ. That would not be fun. I suggest you try to get this resolved as soon as possible.
