New Jersey has public transit, but not statewide. Mostly limited to getting to and from NYC, NYC to Shore Points, Philly from some places in Southern New Jersey.

Don't move to Somerset County, Hunterdon County, Morris County, Warren County, Sussex County, Most of Passaic County, Western portions of Union County next to Somerset County. Not too sure about anything south of Princeton but the less population, the less transit. The more farms, the less transit are pretty good rules of thumb.

Where there are county systems, some are decent, most aren't. All have big limitations in terms of when they run. You can't use Somerset's for work because it doesn't run on any type of holiday.

Hunterdon's is far better than Somerset's, but is still limited, doesn't run on Sundays. Somerset concentratres on getting people to and from Dialysis, really.
