There are two species of toads in New Jersey, the American Toad (Bufo americanus) and the Fowler's Toad (Bufo woodhousii fowleri). Based on this picture, I couldn't differentiate between the two.
Here's a link, see if it helps you:
I agree with you Aaron, R. hamatus it is, though I had to look at quite a few pictures before I found one that made me feel comfortable with that agreement. The fringe along the wings was killing me, but it didn't look anything like either of the other two Rasahus species available.
