Well it is getting late for fall planting in zone 6. Most fall crops would already be planted a month or so back. But if you have some short-season (low DTM) seeds for lettuces, cabbage, spinach, chard, kale and such you might still be able to get a harvest from some of them. And you can still get your garlic planted if you hurry.

If you can enclose them in a low tunnel or a clothe of some kind to add a couple of weeks to your season and keep the soil warm enough they will do ok.

Google 'fall gardening in New Jersey' pulls up several fall gardening discussions over on the New jersey Gardening forum here you might want to check out.

Like Dave said, It's kinda late but you may also be able to pick up some transplants if your area calls for things like broccoli and other longer DTM veggies can go in this late. A lot of brassicas et al can hold up to LIGHT frosts pretty well.
